I was in NYC walking down canal street (chinatown) back when I was about 20 years old, with a bunch of my friends one afternoon. My friend Paul is a crazy guy, and I told him to go and chase the pigeon down the street. When he took off running, I snapped the shot with my Vivitar point and shoot, and this was the result :)
Sometimes you get a conceptual image by accident...this one could portray escape, stress, moving away, luncacy - you be the judge!
