I've been shooting twice downtown at about 3 in the morning before. You'd be suprised by all the 'crazies' you see out there at that time. So I was basically trying to get some good shots and watch my back at the same time. One guy did ride past me on a bike really fast....i didn't even hear him coming until he was right in front of me. Scared the bejeebes out of me...lol
