Apparently, the address on the building door was not spelled correctly. It should read 1411 Nicollet, so it's no wonder why there's no children there.
10 military aged men tried valiantly to resolve the problem, but unfortunately could not figure out how to change the stickers on the window.
So they opted to tape 8.5" x 11" sheets of paper on the window with the address correctly spelled. Problem solved, right? 🤦♂
