Gum Wall & Ladder, Seattle WA
One of the most disgusting and transfixing interactive human art displays (can we call it that?) you will ever find is the well-known gum wall in Seattle Washington. The question begs who was the first to stick their gum here in the first place- and how did it go this far? The City started rumors / efforts to clean it up in 2016, so you may be too late to see for yourself. Of course, this alley might be better witnessed from the safety of your home anyways...
