I once read an article in a magazine about pot growers been seen carting an M-60 into the woods. Then when authorities went in to cut down a large farm, they found plants booby trapped with det-cord running up the stalk, with a detonator rigged to blow the stuff if the stalk was bent in order to chop it off near the ground. I have handled an AR-10 with night scope that was found in a pot field in central CA. It is indeed a war out there...
