I decided a long time ago the only way to handle walking night hunters is to get within 50 yards of and unload a 12 ga 3" turkey gun on their asses with #8 shot, run it dry and leave.
My guess, an its only a guess, is the popularity of game cams act as a deterent. When ever I read about one getting stolen, I question if a night hunter on foot got it after it got him. Also, at least in my area, we don't have the hard, tough, country outlaw that a 10 mile walk in a 40 degree rain is a mere inconvience.
