Man In Bar, copyright 2000 Jeff Spirer
Yes it's another bar shot, but these days, when the streets are empty, this is where I find them.
Running into a really interesting face - 50% of the time, they won't let you take their photo. The other 50% of the time, there's no way to get a good shot. This was that one other time (OK, my math is a little bit off here) when the really interesting face was willing and in the right place at the right time.
