I'm a trusting soul and it's bit me only a couple of times, mostly at home. Last weekend we left campground to come home for a graduation party, had my truck parked on an unused site (took wife's Yukon), gave the keys to the guy in the site next to it in case it needed moved while we were gone. Met him only once before. Never thought a thing about it. I would much rather someone take my stuff than to damage something. Vandalism is the same as theft, but just senseless.
Edit: It did bite me in Goshen when a group of individuals decided to leave about 50 rubber dicks hidden inside my camper!
