I can say i have had a sign at the front of my drive way that said-- ANYONE CAUGHT TRESPASSING WILL BE SHOT ON SIGHT. It was at a house we used to own about 5 years ago, at front of drive way on the gate post. [a gate we closed and locked when we left] Reason was we lived way out on the back roads, people would dump trash on the sides of the road,shoot deer from the road, go 4 Wheeling through people's corn field's just what ever they wanted to do. The sigh was TRUE. I once opened up on a guy one night with my AR15 dumping trash on my property, good for bought of us the trees around him caught the bullets.
