I'm probably going to hell for saying this, but if I was sitting there in my apartment and I saw some dude freaking out because of a sidewalk painting, I'd be laughing my *** off.
That should be washed away immediately. what about the poor people on crack? you think they will be able to tell its just a piece of art? no they will fall into it and then go through a 10 hour hell trip. this is a danger to the "Average" man.
