I know a guy in MI here that went to TN for a 3 day mini vacation once and on his last day there,? he was detecting in a "Battle field zone" where "supposedly" there were signs posted around the area saying "No Metal Detectors allowed within 2 miles" but, he didn't notice any of the signs, and a TN state trooper pulled up and took all of his finds, his detector and, his digger from him, and gave him a ticket that he had to drive back to TN from MI here to appear in court for AND he got a $500 fine.
I never seen a guy so mad and depressed at the same time.
