Lots of stories about this stuff. A friend had them steal the gas from the bed, of his truck. I told him to take an old container, and put diesel in it instead of gas. Sure enough they came back some time later. Don't know what it did for their gas engine but it must have not been favorable. A day or two later they knocked everybody's mail boxes down with a baseball bat or something. Our Policeman caught them. I'm not sure what the penalty is for destroying mailboxes but I bet its' more than for stealing gasoline. I had thought of leaving a gas can full of something near the end of our drive, to help discourage them but conscience said no.
