I have a ton of problems with trespassing and littering by my place. Just this past winter someone dropped off a really nice 18'tri-hull loaded with shingles. Luckily most of these people are dumb, this guy left his registration numbers on the boat. Several other people in the past left bank statements, pay stubs, mail in their dump pilesetc. A guy this past fall dumped a freezer, someone I know saw him doing it. A buddy and myself threw it in my truck, backed in his driveway and returned it. I've tried to be nice in kicking of trespassers, he only way you get any respect is to hammer them every time.
