Okay, I gotta send you all a pic of an historic alley near me called "Bubble Gum Alley" (May be a week, or so). For the last 50+ years, people have been sticking (no pun) gum on the walls of this alley. Some are just a bit of chew, others spell out a certain "history". Very cool, or very discusting. Considering what anthropologists go through, I think this is "high" art...
