dude, I fucking love looking at a good painting too, so i can totally understand that. I can also understand the thrill of trying to do a painting 50 feet up in the air on a building, hanging upside down over a highway, or whatever. And can understand the thrill of public art.

But writing some less-than-funny made up initials on someone else's door or a street sign? b-o-r-i-n-g and annoying. If you want to break the law or break down society's conventions of what art is, might as well do something cool with it, or make someone think about something other than "damn, that's gonna cost me $200 to remove!"

Or, if you wanna scribble or need to practice, find a place that either doesn't matter or where you're allowed to.
