No, but you basically had to have sex in on the ground in front of them to get into the "Carn'Evil", except that when you completed everything you were told that it wasn't open yet, you had to put your name on a list, and come back later. When you came back later, it still wasn't opened. When you came back even later, the whole works was shut down. I filled my card out easily and had fun...
A female friend of ours performed oral, anal and vaginal sex with her companion, in front of a bunch of men and a handful of (appreciative) couples, trying to get in. While she appeared to enjoy the acts initially, she -still- couldn't get into the back although her mate got on the list as easily as I did. After awhile she said she wasn't going to sacrifice her Burn so that a theme camp could gawk at and grope her. (Having to crawl under the craps table and grope somebody's balls, after doing the above, was the last straw.)
Later that night we were talking about it at the Playa-Go-Round and an eavesdropper claimed to have snipped the zipties and slipped into the Carn'Evil, stating that there was nothing at all back there but a maze of tarps...no decorations or anything except a zombie mask he claimed to have stolen. (Which we told him was way uncool.)
None of the members of my camp who completed the tasks returned to participate in the back because it was never open. At one point we went by to see if it was open and all we heard were a bunch of people in the darkened tents yelling at each other, clearly audible on the esplanade.
I don't fault them for controlling the amount of single men, though. At one point some guy in street clothes was walking around with a card showing a woman performing a DP, and he asked my partner and the other girls in our camp to help him complete the tasks even after they'd already politely declined.
Had fun, personally, and my partner did for awhile too. We'd have gone back, but she, like our other female friend, said she preferred to spend her Burn at Burning Man, not in a tent.
Seemed like a fabulous idea, though. Better luck next year.
