Once, there were kids playing on the rock above. I heard the sound of a bottle breaking, and quickly ducked as bits of broken glass showered down over the edge. Then there's little kids who throw stuff over the edge. And last time I was there, some big kids trying to do some "parkour" off the rock. Oh yeah, and some bum left a nice steaming package right in the right downclimb path.

It's definitely a different scene than most bouldering areas.
