Yesterday’s Construction Site Du Jour was a Karl Fischer building and so is today’s. This Pit of Death at 120 S. 4 Street is a building site that hasn’t been touched in so long that its foundation has become nicely tagged up. (The site was originally cleared and excavated a loong time ago and it’s also open for visitation on and off for years.) The drop, right beyond the hole in the fence is one or two stories down. Watch your step.
