You can walk along the perimeter on green lane "W.E. Kurtz & Sons" Building on certian sides

Not the biggest deal ever, i do imagine a Lash going up there and causing havoc in the future for green lane.

You can not jump on this from the accessible side where the creeps spawn. but you can reach the perimited from every other side of the building. I have not tested this on other buildings but this should be patched out
