I recently had an experience with one of these wacko's. I was bowhunting a NWR in Louisiana on a day birdwatchers were counting birds. I was walking to my truck to take a break when this couple came up asking what i was doing! So I politely said "hunting". I decided to go back in the woods to get away from these two cause they looked to be plotting something. When I came back, someone had taken a dump on the hood of my truck, which has 35" mud tires on it. I just wish I could have got it on camera!
