Happened to me last year,got set up on a bird before dark. Working him toward us off a ridge above us,a guy riding down the road heard the gobble,pulls over comes at me and my buddy in a hurry,ran 2 Deer making a racket right up the ridge where the bird was. Flashed our lights at him,kept coming. He walked within 30 yards of us drove the bird away and did not even apologize when we stood up and said what's the deal man? He walked right behind us up the ridge and acted lik we did not exist. Morning over. My buddy who is not as forgiving as me wanted to follow him and ruin his day,but I said lets go,he ain't worth it. We both got great birds later on.
