Harrison FYI: I discovered last year after a friday night Terry's Terrace excursion, that security closes and locks the gates to the pits sometime between 11:30 pm and 2:30 am. The big fence with the rows of barbwire on top is scaleable to get back to your motorhome. You just have to be drunk enough to think you can climb 7' of chainlink with 3 rows of barb wire on top if it, and just sober enough to pull it off without killing yourself.
Good thing Im the medic safety guy, I figured if I wiped out, I could fix myself
