I like this one. It actually looks like these long-abandoned buildings in the Marin Headlands are occupied again and full of life. This photo required a VERY long exposure time (three and a half minutes!) and involved lots of running around between buildings while popping the flash in manual mode. Check out the aerial streaks made by the stars and a lone airplane moving across the sky. The reddish glow in the distance is from traffic on U.S. 101 just over the hills.
