I think the bear trap/ tiger trap, big deep hole, covered up, is the way to go, try getting their ATV out of a hole like that? sounds like freebie 4 wheeler to me.

Though the best thing and most responsible action is probably to get them on camera/video, report it to the police, and press all the charges you can to the full extent that you can. No warnings, next time I catch you BS, if you catch them, nail them!

I have had the thought to make a billboard and list the names of those I've caught, prosecuted, and the punishments/fines.

The felony damange to property/crops etc...sounded good to me, like I said any thing you can bust them with, do it! don't feel bad, people need to learn illegal is illegal, I don't care if you won't do it again etc....

Give someone an inch, and they'll take a foot. Locals start to hear that you're you bust everyone no questions asked, they'll stay away.
