What's the WORST Experience You ever had at a RV/Camp site?

Back in the early seventies buddy and I rode bikes from NW Ohio to Toronto to Mosport track for a Can-Am race. Tented in infield in our small tent, sleeping on air mattresses. Infield was sand roads with dirt bikes and dune buggies. Then the rain started, lots of rain! All nite rain with riding still going on, lit with only the few pole lites. The riders were as brown as the sand roads. The only reason we slept dry was our mattresses elevated us above the flooded tent floor. Got up the next day to potable toilets full above the seat! Needless to say we spent the second nite in a motel. Dave
