When calling to mind the Los Angeles Philharmonic, everyone’s (and all the posters’) focus is on Gustavo Dudamel, (or, the Dude, as I call him), all unruly hair and visible enthusiasm and so forth, and that’s great. He’s an excellent conductor. However, one of the unsung (as far as I know*) visibly spectacular performers of the LA Philharmonic is the excellent principal viola player whose name I do not know [update: see below*] who puts on the most remarkable physical performance every time I go (and presumably those other times too). Actually, the violist who sits next to her is also remarkable, since she manages without being distracted by her neighbour to maintain a very upright and solid, firmly planted, legs wide stance, in part providing a canvas upon which the viola player I first mentioned can splash bright splashes of movement all over the place! She rocks, sways, jerks, and contorts (sometimes even during quiet slow bits)- doing the craziest things with her legs, head, and bow arm, and so much of the time looks like she is about to spectacularly fall off her chair and wipe out at least half the viola section! This is why her colleague right next to her is also remarkable, as she acts as this wonderful un-distractable “straight man” to the physical pyrotechnics helping make them all the more remarkable by contrast. Last night I tried to capture some of the energy of the hyper-energetic viola player in a quick sketch (during [...] Click to continue reading this post
After a long weekend of a two-day meeting of an American Physical Society committee (hosted in LA this time, so I did not have to travel far), I decided last night to go and do a drop-in-and-draw session at an art studio, to clear my mind.
The model was excellent, with a smashing hairdo and good body-awareness that made for interesting poses. I was in the mood to disappear and listen to Hendrix for three hours while focusing on the simple task of representing what was in front of me. So I did.
I’m horribly slow again. Lack of regular practice (on full figures), of course. The good news is that I have been able to hold on to some of the more important foundations that allow me to lay things out, and see forms and shapes. But it does mean that I don’t get to get to some of the finishing processes that I intuitively prepare for in the earlier parts of the drawing.
As you know from many posts of mine on the subject (see e.g. here and here) I actually like incomplete drawings where you can see a lot of the process [...] Click to continue reading this post
There is always a mixed set of emotions for me when I come to change notebooks. It means that I stop carrying around pages and pages of ideas, impressions, sketches, and other things from the last few months that I can accidentally stumble upon. Instead, I start a whole new blank book that does not connect back to anything. I must fill new pages (which I love doing) that will become those favourites I will look back on. So I always like to start off with a drawing that I’ll like to look back on. It helps set the tone for the pages to come in the many months. (See an earlier post about this matter here.)
Yesterday gave me a nice opportunity. I took my mum (who is visiting for a while) to the beach in Santa Monica and we walked together on the sand for a little while. I then sat on the sand and did a sketch while she continued walking and looking around. My focus was the Santa Monica pier, and I wanted to [...] Click to continue reading this post
Holiday time is upon us, and in this part of it, it is coming up on Christmas time. Really fast, it seems. The semester sort of petered out mid-week for me with the submission of the final grades for my graduate electromagnetism class (everybody did really well… fantastic group of students this year), and one last two hour committee meeting for another of those committees I can’t tell you about. I’ve found some time to think about some physics, and work on a new page for the book, among other things. There’s a panel [...] Click to continue reading this post
Finished the inks and threw some (digital) paints over the lunch group. I think it’s time to move on to another part of The Project. I’ve spent far too long fiddling with the light in this.

Actually, this new tool is pretty old school, and I love it! There are times when I want to have a change of venue while doing rather detailed work for The Project… perhaps go sit in a cafe for a change, instead of at the drawing desk. But when not at the drawing desk, I could not use the lovely large illuminated magnifying glass […] Click to continue reading this post
Well, since yesterday was all about eating here in the USA (Thanksgiving, in case you missed that), I thought I’d share a partially inked panel from The Project, of a meal in progress. I got a bit of quiet time to work on it this evening, while listening to Jimi Hendrix and then Freddie Hubbard. They helped a lot. It is at times like this I wonder what insanity has come over me […] Click to continue reading this post
Sunday saw me spend a bit of relaxing time in the morning at a breakfast bar sketching a colourful pan of tomatoes, apples, and a yellow pepper. I spend ten minutes doing a quick pen and ink outline sketch of all the elements, which was fun and pleasingly simple enough.
But then I decided to lay on some colour and so pulled the sketch into Brushes on […] Click to continue reading this post
It has been a long and tiring week so far and I decided that I needed to withdraw for a little while. So I left campus early and went on a wander downtown. My goal? It is the last day of the worldwide Big Draw month of October (but see below*) aimed at raising awareness of drawing (you may have seen events in your own town – maybe even participated in some), and I’ve been so busy I’ve not done much outdoor on-location drawing this month (not counting subway drawing) and so I thought that I’d get one in on the last day. My own little contribution to the local Big Draw LA, if you will.
Anyway, I considered doing some well-celebrated landmark like one so many of the splendid buildings available (Union Station, Central Library, Eastern Building, Walt Disney Concert Hall…), and as I walked I pointed myself in the direction of some of these, but just after I turned away from the library on Fifth, heading to Pershing square, I saw what I wanted to draw. If you stay on […] Click to continue reading this post
Managed to find a little time over the last few days to lay out, draw, and ink a page in The Project. It has been insanely busy for me, so this is a little bit of a triumph in stealing some time back. It’s actually the same seminar that you saw in earlier posts (here and here). Now it is over. It remains a tradition in our field to give a little round of applause after a talk, which I find rather nice and quaint. It was a pleasure to depict that.
It is a wider view of the room, which meant (aaaargh!) drawing even more faces and bodies than before. Then there’s the challenge of doing them in different states of attention, applauding, with different faces, bodies, states of dress, etc. When I come to paint it I’ll be wanting to pick colors that together communicate the right mood for the panel and for the whole page it is part of, and so forth. It can be daunting to do all those faces, bodies, shirts, feet, and […] Click to continue reading this post
I realized just now that since I set a midterm exam on Monday for the graduate electromagnetism class, and since there’s only one midterm for the class, it really is… midterm. The semester is sort of half over already. And indeed, a glance at my calendar shows this to be more or less true. I’ve mixed feelings about this since on the one hand it is a busy and tiring semester and I’m glad to have it go by, but on the other hand… slow down life! What’s the rush!? Yes, I definitely keep wanting to make sure I stop to smell the flowers, or what’s the point?
The midterm itself (Monday, in class) was fun. Or at least, I found it fun to put together on the weekend. There were no complaints from the students, so I hope that means I got the balance about right. We shall see during class tomorrow, when [...] Click to continue reading this post
I must say that I had fun doing this drawing (click for larger view), and it was a long time coming. After returning from New York I decided that after a lot of tiring travel back and a long day of work the next day that I would keep the momentum from the plane drawings and go and relax and do a drop in and draw at a studio for a few hours.
It has been a long time since I’ve popped into a studio to draw a model and I am happy to say that I was not as frustrated in the end as I thought I might be due to lack of practice. (In fact, it is best to try to enjoy getting done what you can get done, and not get frustrated since that just makes things worse…) I was a bit slow, yes, but was happy that the processes of how I draw best came together readily, and by the [...] Click to continue reading this post
I’m going to admit something maybe a little naughty right now. One of the things I was most looking forward to about the whole New York trip was the plane ride so that I could spend time drawing. It has been a long and busy several weeks into the semester already and that means that I’ve been not getting as regular drawing practice in as I’d like. So the airline downtime (blogged about here and here) is actually rather a welcome activity since I can bring out the sketchbook and draw. I’ve been regularly requiring myself to work directly in ink, so this means no correction of mistakes as one goes along. To proceed in drawing, you incorporate poor decisions about lines you’ve made into the drawing if you can, and move on. It also means that you learn to look more closely and think a bit more about line choices, and what you’re trying to capture.
Anyway, this fellow was sitting on a hydrant on one of the streets bordering [...] Click to continue reading this post
Well, not a lot to say except that this is the painted version of the panel you saw a few days back, part of a page of the graphic book starring science that I’m working on (follow the link for more). Was a long time coming, this page. Too many [...] Click to continue reading this post
Another fun combination of science and sketching! Photographer Volker Steger decided get his subjects – a selection of Nobel Prize winners – to try to represent their work (what they got the prize for) with a drawing.

You know those cross-country trips that nip from one coast to another for a day and then back? There are people who do that regularly for a living. Honestly, I don’t know how they do it. I left LA on Monday to go to a meeting in DC, and returned on Tuesday night, and while nothing unpleasant happened en route (and the meeting at the DC office of the American Physical Society was good), it is really not something I’d make a habit of. I like to add a bit of time to see the place I’m visiting, and get a bit of a feel of the pulse before flying back. But there wasn’t time. I was in DC for a day and a half last November to visit another organization, and I did manage to get two hours to wander the mall and have sandwich in the cafe of the Smithsonian, but I’d have liked a bit more time back then too. Anyway…
I did, however, get some face time. On take off on the flight back I flipped through Hemispheres (United’s in flight magazine) to see if there were any more large faces to sketch. (You’ll recall several earlier posts about my liking to do this for practice [...] Click to continue reading this post
Yes, I found a bit of time to work on a page of the book. Here’s the development of a panel (click for larger view):

I spotted* this lovely post from a year ago about colour, culture, and language that I thought I’d share. What does the map of colour and colour names look like as you move from culture to culture. And are there universal aspects to it, or is it pretty random?
I find this a fascinating topic, and so was delighted to see this post, which addresses a lot of the questions. (You’ll find links there to an episode of Radiolab that was on a similar topic. I recommend that too.) Coincidentally, two pages before the part of my notebook where I’m doing a computation right now is a [...] Click to continue reading this post
While in Griffith park yesterday evening I looked West when near the top of a rise and saw one of the great sights you can get at this time of year. The stretch of the Santa Monica mountain range coming in from the West shrouded in the mists rolling in from the West. The mist hides a lot of detail and leaves you with just simple layers of shade, almost monochromatic. It was quite beautiful. (Sadly, a lot of people who like to reach for the usual negative cliches about the city assume the mist is smog, but it [...] Click to continue reading this post

Memorial Day was fun. There was a gathering at a friend’s house down near the LA River. At some point in the afternoon lots of people went down to the river banks to look at the lovely scene there, with people fishing, cycling, and kayaking (and other sort of boats) along some stretches. This is not at all what people expect of the LA River, so it was good (once again) to see a different reality shine through the standard images. Focusing on being good company, I only started [...] Click to continue reading this post
On Saturday I decided to have a bit of simple relaxation at home, and sit on the patio with my notepad and some pencils and draw a likeness. I’d not done any practice from images for a while, and frankly my pencil work was very rusty and needed a workout.
So I dug out this month’s issue of a sewing magazine that I subscribe to (what?! well, it’s a long story… let’s move on) that happens to sometimes have interestingly lit and well reproduced photos of faces and sketched for a while.
It was fun (even with the slightly flawed outcome). (Click for a larger view.)

It has been a while since I shared a snippet of the book project with you, so here’s an update:

You might recall that last year I gave a talk at TED Youth, in their second year of short TED talks aimed at younger audiences. You’ll recall (see e.g. here and here) I made a special set of slides for it, composed from hundreds of my drawings to make it all in graphic novel style, and somehow trying to do (in 7 minutes!!) what the TED people wanted.
They wanted an explanation of string theory, but when I learned that I was the only person in the event talking about physics, I kind of insisted that (in a year when we’d discovered the Higgs boson especially!) I talk more broadly about the broader quest to understand what the world is made of, leaving a brief mention of string theory at the end as one of the possible next steps being worked on. Well, they’ve now edited it all together and made it into one of the lessons on the TED Ed site, and so you can look at it. Show it to friends, young and old, and remember that it is ok if you don’t get everything that is said… it is meant to invite you to find out more on your own. Also, as you see fit, use the pause button, scroll back, etc… to get the most out of the narrative.
I’m reasonably pleased with the outcome, except for one thing. WHY am I rocking [...] Click to continue reading this post
Well, since some of you are curious about how the page might look in final form, given the (nicer than normal) rough I showed you a little while ago, I thought I’d show you. (For those of you not following, this is part of the graphic science book project I’m slowly working on. More here.)
I got carried away and decided to properly pencil out the whole page and ink it fully, and then I painted the same panel as before. Now you can see more carefully rendered faces according to the design I chose for these characters, and you can also see the backgrounds of the setting a bit more. It is another real location, a very well known place in Europe. (Actually, I spent some days doing research online to try to reconstruct the details of the interior from tourist photographs, and reconstructed [...] Click to continue reading this post
It’s that time again. I finish a notebook and start a new one. A new book is begun with writing my name and contact information in the front part, in case it gets lost, and an old one is ended with mixed feelings, and that ending is often a bit drawn out. Notebooks go around with me nearly everywhere, and have pieces of me in them in one shape or another, and so it is hard to stop carrying one and start a new one. I’ve got bits of computations, shopping lists, partial thoughts about projects, design sketches, doodles, snippets of silent conversations between me and another person at a concert or talk (writing it down is often less distracting to neighbours than a whisper), scribbled phone numbers, film, book or cd reminders, and of course lots of practice sketches and doodles on trains, planes, and in automobiles, done almost on a daily basis, sketches done in (and sometimes of) an event, or of a interesting place or structure. (You’ve seen some of them here on the blog.) Almost everything has a date written on the page, or on a page nearby, which is hugely valuable.
It’s a combination of notebook, journal, playground for ideas, and more. It is a joy to just open it up and flip through it and see so much of the last few months of my life and thought spread out in ink and pencil (and sometimes watercolour). Sometimes I hit on a particularly successful or interesting (or both) drawing that I love to open up and look at from time to time. You can search the blog under “sketches” for things that were in previous books. For example, a few of my favourites from this book are: Sketch of C. Tyler during her talk, sketch during a committee meeting, airline sketch of a national treasure, other airline sketches, a nice grab of a face from the subway, another airline sketch.
All of that now gets put on a shelf, since the pages have run out. It is bitter-sweet, as I also like the analogue, finite nature of the whole business. It has a lot of life written [...] Click to continue reading this post
Well, yes, I’ve been a bit busy and so posting has been slow over the last week. But I am still alive, and here I am with a sample of one of the several things I was doing. It is some work on the graphic book project. (You’ll be happy that I am sparing you details of tedious committees, faculty meetings, confusing snippets of physics, incomplete musings and computations, etc…)
As mentioned recently, I’ve been doing thumbnails and rough page layouts on one of the stories, and that has been useful for editing and rewriting. I went further and improved an earlier story that I’d written that had mostly been drawn already, and so that encouraged me to do slightly tighter page layouts so as to fit them more closely to the story as it was already drawn, for a smoother final read. I’ll need to find [...] Click to continue reading this post
Well, I am coming to the end of the week of hiding away in this undisclosed coastal town, and I can report that it was very good for me. I managed to get enough immersion to work hard on one of the stories for The Project, and this morning I read it through (I actually broke it into two stories) and turned out to be not too bad so far. Hurrah! Reading it next to the completed rough visuals really helps. I wish I’d had time to work on more stories, but that’s for another time. I’m just thankful to have had the time to have a good focus on one.
Wednesday I went back to that studio I visited on Monday as they were having another drop in and draw session and I felt it would be a nice end-of-long-work-day relaxation to go again. The model was actually rather excellent, and I wish my speed was a bit better to catch some of her faster 2 minute poses since she had a great [...] Click to continue reading this post
Productive day yesterday, more or less. Yesterday’s lunch break (in my undisclosed coastal town) saw me take a pack lunch over to the beach, for a bit of reading while I sat in a change of scenery. I’d brought the bike, and so it was nice to be able to pack up some things I might need, like a beach towel, a portable seat (just in case…. I did not use it in the end…), my notebooks, and some reading materials on the ipad (I was reading a bit of Paradise Lost, in fact), and carry it in the bike basket. (Actually I did use the portable seat… but not for sitting. I used it as a stand for the camera that took the shot above right.)
What am I doing on The Project? I’m mapping out and editing one of the stories. It has turned into quite a long one with lots of complexity, relatively, speaking. This means that I need to be careful about designing the layout on the page, and actually try to get a good sense of how everything fits so that I pace things properly, and page things out in the right way. So I am thumbnailing carefully, going beyond simple thumbnails and doing a first pass rough of the page. It slows the writing down, but will save a lot of time later on. Also, when I turn myself back into the penciller/inker and come to draw all the pages carefully, my job will be much easier, and quicker, as I’ll have the directions in the written script and the page layout sketch to guide me. I’ll be able to focus more on being the artist and less the writer at that stage. See the right for a laid out page.
Actually, using the brushes application on the ipad has been very valuable for this. I’ve not used it much in recent times, and so it was fun to rediscover it. I’ve been using [...] Click to continue reading this post
Probably not really the appropriate use to mean “on retreat”, but it makes for an interesting title. Anyway, I’m on retreat for a week. As you may know, I am in the habit of disappearing for Spring Break, and I try to get away from it all (or most) and have some time to myself, and maybe also work on a project. You will recall that Death Valley is often a destination, but for what I wanted to do this Spring Break, my old haunt won’t work. So instead I am in a small town somewhere on the California coast. I’ve set up shop in a little condo I’ve rented, and I’m trying to get some writing done on The Project. I need to do a lot on the computer, putting together a lot of the material and scripting it out properly, which also involves planning and thumbnailing the pages. This is a slow process that needs lots of immersion, and I’ve not been able to do that this semester much… so this is why I’ve devoted the Spring Break to it. My routine so far has been to go for a short run on the beach first thing in the morning (not for long….I am not a runner really, and only like running on surfaces like grass, and sand that don’t hammer back too much, but it is exhilarating to do a short run in the morning and get all the juices flowing…) and then sit down to work over breakfast. But since this is really day 2, it is not clear if this is really a pattern or not.
This afternoon I sought out the local “drop in and draw” session to do a bit of life drawing from a model. Just as I’ve mentioned before (see two posts ago for example) you can often find such things in your local town, and it is not too hard in areas such as coastal California towns since there are lots of artists living in such places, and they seem to like and appreciate the value of life drawing practice. So I showed up, paid my money, and went into the studio and drew. The people were welcoming, did not pry too much into my business, and it was quite [...] Click to continue reading this post
Well, yes, I’ve been very busy with several things. After clearing away a lot of them, I decided last night that it had been long enough since I’d visited a “drop in and draw” studio to practice figure drawing, and so I went along. (I’ve written about this on previous occasions…you drop in, pay a fee towards the model’s salary, and then you draw. You can find such studios in your own city if you wish. There’s nothing like live figure drawing for practicing observation, hand-eye coordination, and a host of other skills that need regular maintenance.)
Anyway, I dropped in, said hi, started up some Kate Bush (“The Sensual World”) on the ipod (followed by Mayte Martin – “Al Cantar a Manuel”) and I drew. A great and [...] Click to continue reading this post
Continuing my recent series of short trips around the country for various reasons means that I continue my series of that fun pastime and practice routine of flicking through the airline magazine and finding interesting people to draw (some recent ones are here and here). I did three this time, and here are a couple.
The first one was a quick warmup (I cleaned out some lines since it was on top of another drawing), and it turned out nicely although it looked not a lot like the actual [...] Click to continue reading this post
Last night I went to a nice event as part of the Visions and Voices series. It was an interview of (perhaps conversation with is a better way to describe it) writer and artist Carol Tyler by Henry Jenkins, who is a professor here at USC in the Annenberg School of Communication (check out his excellent blog here). C. Tyler is well known for her work in the comics and graphic novel world (or graphic book, if you prefer) particularly in the underground comics movement. She is one of the most well known memoirists in this medium, telling the story of her family life, and in particular a great deal of her father’s retelling of experiences in war, and its effects on him, her, and her family. It was good to go along and listen to her talk about her journey in producing the three books that came out of that project (“You’ll Never Know”), other projects, and a little bit of her personal history as a writer and artist. (See Henry Jenkins’ post about her here, and her own website here. Many of her books are published by Fantagraphics.)
I met and spoke with her
last year (update/correction: two years ago) very briefly (she certainly won’t remember), since a few of us (including her) were waiting in the lobby of the LA Times building for the LA Times Book Prizes ceremony to start. She was a nominee in the graphic novel category. We talked for a few minutes and then went in. I remember being struck by [...] Click to continue reading this post
So, after a bit of time away from the process, this weekend saw me make some progress on The Project. I realized that I had too many things fragmented, scattered in several places, both physically and in my mind. This means that when I come to pick up where I left off (and breaks from it – sometimes long ones – are necessary since I have my Physics Professor gig which is first and foremost, you understand…) it can take all the available time to get back into the saddle since I am pulling the fragments back into foreground. So I’ve decided to sharpen up the process a bit and try harder to send clear notes and assignments to myself in the future. For example, as writer, I need to prepare things so that they are in a good final state with clear conventions in a full script, so that when I come to it later as penciller, I’ve got all I need to get stuck in and move things along, sending messages along to future me at the next step, and so on. It means I’ve got to do less of the business of leaving things un-fleshed out because I think I’ll do that bit at a later stage – That later stage might be months down the line, and by then I’d have forgotten the core of the idea that I was going to build in at that point… You get the idea.
So my task for the next several sessions is to turn all the stories I’ve written so far into full scripts, and finish the bits that are unfinished in each one. What do I mean by full script? Well, over the last two years I’ve done a lot of it in notebooks and in [...] Click to continue reading this post
Another dude you may or may not recognize. This is for those of you who wondered who I’d find next to do a sketch of, and is another of those sketches done in the cramped conditions of my airline seat after browsing through a magazine to find an interesting face. See the previous post on this practice. There’s this series of print commercials for a watch or something similar that has served me well with well-lit faces, and so when I thumbed through this month’s Hemispheres, I was quite pleased.
I did this one with a mechanical HB pencil, and it is quite incomplete… there’s a bit of tinkering I could do with the modelling of the cheeks and around the [...] Click to continue reading this post
[Update: replaced sketch with the painted version.] I managed to get a sketch done of some of my colleagues present at the meeting I’m part of here in San Antonio, TX.

While I was apparently catching that horrible flu virus early last week during the travelling I was doing, I was killing time with a few sketching games I tend to do while travelling. I was grabbing faces. A moderately careful face grab is to look through whatever magazines I have to hand (such as the in-flight magazine) and see if there are interesting faces… then I might do a quick or longer drawing of one or two that I find. Sometimes they are familiar people, as is perhaps the case with the one I show to the left. This was not intended to be super-careful, and was rather quickly done, but it turned out to be nicer than I expected.
I was simply drawing with a pen and not trying to be very accurate, and just capture expression and structure of the face, but my eye was in and so… (I’d have used pencil if I was planning to go for accuracy…) I liked it enough to finish it up when I got home and throw some watercolour (pencils and then water brush) on to it. (I took a quick snap of the magazine photo before I left to allow me to recall some features for finishing.)
I’ll spare you the other ones I did in that mode. Not for public consumption! [...] Click to continue reading this post
Sort of stuck this morning. I was up at 6:30am (more or less my usual time these days) with good intentions to get back to do a nice stretch of work on The Project for the first time in a while. But it is almost 10:30am and I’ve done nothing (not counting procrastinating, making fruit compote for pancake breakfast, sending a bunch of emails, and so forth).
It is difficult sometimes to reboot back onto task on a project when one is suddenly done with one of the major things pulling you away from it. Classes are over, you see, and so I am transitioning into a different mode, and not super-efficiently.
I think maybe before I have to leave to run errands out in the world (after lunch), I must get something done toward [...] Click to continue reading this post
Penultimate lecture today in the graduate electromagnetism class. These last four lectures are a lightning tour through some important concepts – showing how many of the things we’ve been doing all semester fit with Special Relativity. (For example, amusingly, showing that the Lorenz gauge condition is in fact Lorentz invariant…) It is fun to show a powerful example of how an important guiding principle (such as writing equations in a Lorentz-covariant way) can end up making several features of the theory seem much more natural, while also leading to new physics. This is fun to do, although it does mean that I end up writing whole new notes for this since I am not a fan of the way some of these electromagnetism books (Jackson included) decide to treat time in an odd way, such as treating it as imaginary (which must be so confusing to some students) just so as to write Lorentz transformations like a rotation, or using mostly negative signatures for spacetime, and so forth. And, inexplicably, using different units of measurement from the choices made in the rest of the book… Anyway, so the last two lecture-writing sessions have mostly been one of fiddling with minus signs and factors of c, 4 Pi, minus one, and so forth. Joy. Well, the group seems excited since they’re beginning to see things that they’d seen in other classes and it is all making some sort of sense now (Klein-Gordon equation, duality, etc., etc…) I think the last class will show how many of these things flow from variational principles. Maybe I’ll find a little time to do the Born-Infeld model? I’m excited too, although I’ll be sad to end the class and stop working with this fun group of students.
Today I managed to grab a few sketches on the train. This afternoon coming home on the Expo line these two snoozing gentlemen were kind enough to sit still for a few minutes each for me to get down a few impressions of their features. This was all helped a bit by the train sitting still for a while as we waited for a truck to get off the line. Apparently it was parked or stuck there.
Perhaps not helpful was this young guy who watched me drawing and then decided [...] Click to continue reading this post
