I have fire arms and an expired concealed permit.I don't plan on metal detecting in an area that requires me to carry a concealed weapon.There are too many safe places to hunt.I try to avoid confrontation as much as possible because there are a lot of stupid people just looking for trouble.I use to coach soccer a few years agne point I would make to the team,I would shove a player on the shoulder enough to knock them off balance and startle them the second shove an anger look and ask the player now what are you going to do! Right before the player retaliated I would answer the question for them.When this happens walk away you don't have anything to prove.I agree there are times you can't walk away and have no choice to protect yourself.Most of us know where the trouble places are and I choose to hunt at another location.By the way anyone want to go on a group hunt to Mexico,just kidding.
