One summer camp I worked at there would occur the occasional race weekend when the local track would open.  People would often camp out at the race track with no facilities beyond porta potties so they would buy a pass to a nearby State Park to take their showers.  Well on one Saturday afternoon a car pulls into our camp, a young lady gets out and heads for one of our bath houses before anyone can intercept her.  So she took her shower and when she reappeared we asked if we could help her.  So she states she had one of those passes, we let her know she’s not in the State Park, oops.  You’d think she noticed that everyone around her was a child with a few adults mixed in.
