Location: 16th and Blue Island
Remember the Red Hot Chili Peppers song "Under the Bridge"? That's probably what this person was singing while drinking this one. I found it under the disgusting bridge on Blue Island, right before you get into Pilsen while walking my dog. He was trying to lick the remaining contents up. Even he knew that it was a shame to let any of it go to waste.
So this is down the street from the projects, but it's also right near some $350k condos. Your guess is as good as mine as to who it belongs.
