Where the fk you live and what kind of mopar dude hops fenses into other peoples yards. If I even go as far as to stop.. I knock on the door unless I see signs saying "fk off"...then I leave my number at the gate or in the mailbox.
Tarp and strap the cars.
When they are tightly tarped down they are less inviting. Also... put them all next to and in front of each other...so you have to move the least desirable ones to get to the driver door or hood of the rare ones.
If you also use the ratchet straps from link bolted to hood loop to k member underneath... the hood won't come up without them getting more involved.
