I went out on public land one day years back and got up in a real tall pine tree on the corner of 2 roads so i could see anything crossing them or going into the clearing across the road and about day light here comes some guy down the road in his truck he stopped right infront of my stand and changed his clothes smoked a cigarette and drank his coffee then answered the call of nature and drove away he never saw me or had any clue I was there but needless to say I never saw anything else that morning
