I don't... know very much about Graffiti, except that it's incredibly interesting and sometimes really funny. I live by a set of train tracks, and as most people know, that's one place where people do tons of graffiti, I haven't saw quite as much as the years have passed, but I'll probably always vaguely remember it on those noisy train cars that pass through all the time.
Anyways, the whole purpose of this post was to give a link to a blog I came across when I was browsing about twenty minutes ago... ;
