The system works in one tiny case. Or, at least, the laws of coincidence do. We featured this “Hanging Stop Sign” at N. 9th and Wythe a couple of weeks ago. When we swung past the other day, we found it had been dutifully repaired, even if it’s a little low. No such luck with the nasty scaffolding outside 70 N. 9th Street. It’s still in an awful state, with hanging metal, and looks like either gravity or a nice breeze could bring pieces of it down at any moment. Our advice: Walk on the other side of the street.
