Yea, that's what I heard from others as well. IIRC, it was the roof/patio? Maybe not. (It was in the same venue as Shit Show - I'm pretty sure the area people couldn't get to was the patio, since you can only get there by passing through the other rooms). The capacity for the upstairs room is very small, so I'm guessing that they were concerned about how packed that room would get with people trying to make their way to the patio. (I have heard from a few people that the patio wasn't very crowded). That's only second hand info though.
