A new fence laced in razor wire has been erected on the far end of the dam where you used to hop over. Skirting around is a trivial matter, but I'm unsure how the message should be interpreted. There are no new signs indicating closures, and you can still hike over from Stumbling Blocks/Ghetto Wall. If anything the fence is going to have more of an effect on the hikers trying to do the loop than the climbers. On the plus side, I've never seen it so empty at this area.
