Somebody solved the St Louis #Octothorpean puzzle‽

https://www.octothorpean.org/ has many, many puzzles. Most of those puzzles can be solved on your couch; but some involve observing details about some place or other. To solve one puzzle, you need to see some things in a place in St Louis, Missouri, USA. For years, that puzzle has lurked, unsolved.* Until just over a day ago. Whoever did this: Nice work. You now have bragging rights at the next Puzzled Pint or whatnot.

*OK, someone "solved" it a while back by throwing the dictionary at the answer checker. But that's not so interesting.
