I love street art. Perhaps it is the shock artist in me, but I immensely enjoy art showing up in places where you don't expect it. This sign was on the corner of a not well traveled street, so it's probably no big deal that the sign is getting covered, but its nice to see art cropping up here.
It's almost like plants growing in the middle of the city, breaking through the concrete. It seems that they shouldn't be there, but nature finds a way.
