Been kicked out a few times, never been arrested. Trying to explain to people what you're doing is the funniest.
We hit a rail in a parking lot next to a police station one night. A cop pulled into the lot and was just watching from the other side for a good hour, never did anything. We were nice though, helping drunk bitches over the kicker at the top of the stairs.
Sometimes people are cool, sometimes they aren't so cool. Never really know what to expect
