Mystery Van Part Deux

It is no longer a mystery. There is no dead body, no meth lab, nothing mysterious. This is just an RV owned by some local who lives in it and periodically leaves it in an unpaid campsite knowing it won't be towed for 72 hours. The Rangers are wise to this ploy. I was not until today. I am, however, concerned about the group of quiet and polite Canadians at the other end of the campground.
