The other day I was down near the 9:30 Club and noticed the entry way of the building next door was covered in what looks like gum. Pretty weird.
The building is abandoned, it used to be Atlantic Plumbing, so I'm not really sure how the gum got there. 9:30 Club lines don't usually go that far, and the gum seems way too orderly placed to be just random. A quick Google search didn't turn up anything, although the gum wall does appear on Google Street View, so it's been there for a little while, at least.
Interesting, in any case. I guess if you're in the area and the flavor has gone out of your gum, stick it on there!
