What attracts certain people to certain places? This particular building attracts graffiti artists in droves. Their work, in turn, attracts the likes of me. As I took this pic, a woman walked by, saw me shooting and decided she'd like to take a pic, too. Maybe her shot will end up on a wall somewhere as the focal point of an exhibition on urban evolution. In the mean time, I revisit the wall, which is different every day, and wait for the answer.
