I’m 24 hours too late to warn you of the peak, which was this morning, but I imagine it will still be very good over the next few nights. This is the Perseid meteor shower. Apparently it is very good this year. So wander out when it is dark enough and see what you can see. Look toward Perseus, of course. More information here, from the Meteor blog, and the ever-excellent Stardate site gives you some directions (or look here).
In a big city like Los Angeles? Don’t automatically believe the lazy excuse that there is no chance to see astronomical events. Sometimes a little bit of effort, maybe resulting in seeing parts of your city you may not visit much, can pay off. See an earlier post from precisely two years ago for an example.
