Man I'm tellin you, if you wanna stop that forever you will have to catch em and confront em. I struggle with a raging temper myself , so when I catch em it takes all I got in me not to drive my skull through their face and scream like Hulk at em. When you catch em, be polite but firm with em. You can't prove they stole your camera, you dont know who it is yet, although chances are whoever you catch on your property is your culprit. Tell them that you know they took your camera and if they ever set foot on your property again the law will be involved. The thought of law and fines usually scares about 30% of trespassers away for good, from my experience. Catch em a second time, be very stern with em and tell them the wardenis beingnotified of the situation and you might add something like "the landowner knows who you are and knows you've been trespassin, I won't stop him from puttin a bullet in your ass, its his land and he can do as he pleases, good luck buddy." Even though he aint gonna shoot em, it might scare em a tad. I like to view trespassers as terrorists in the middle east. They will always do what they do, and you must keep constant pressure on em and a continual presence in the area to keep em from taking over.You won't stop em, but you can keep emin check. If they see your truck more often, they will less likely take a gambleon any given day. I hatetrespassers with a passion. Sorry about your Cudde, but don't put TWO MORE up. That's askin for it. Maybe set a trap by puttin up an older and cheaper camera with no film or disk in it, and have the old man keep an eye out if he can. Stay at em, post the property, let em know you're in there and it's your place.If you catch em, walk right up to em and look em dead in the eye. I'd say 75% of punks like that are all talk and will cowar down if they know you mean business. They will probably come back, but like I said, all you can do is keep em in check. Good luck.
