Free: Contests & Raffles.
I have never even considered my camp being vandalized, truck being vandalized, or people being mad because I parked somewhere? I go hunting. I hike or bike miles in to get away from people. I don't mind road hunters, in fact I encourage it! Fewer people in the woods messing with me. If anything, over the last few years I've noticed a substantial increase in the number of guys willing to get after it and hike miles in in the dark. Didn't use to see anyone where I go, last year I saw half a dozen guys. My truck has never been vandalized, my camp has never been vandalized. But I don't leave stuff laying around to tempt people either. We keep a clean tidy camp with stuff out of view, and I don't leave anything valuable in my truck. Go hunt where you want to hunt and enjoy it!
Why come back to camp at all? Your stuff will probably just be thrown in the bushes anyway.
