It happens man. A couple years ago, I was sitting on the edge of a 4 wheeler trail facing down towards where my brother was pusing through the bush. I was there 15 minutes, and knew that he had a long walk before circling and pushing back towards everyone else, so i lit a smoke. I figure, if the deer are runnign away from him, they probably wouldn't notice. Then I hear a little noise on the other side of the trail. A maybe 3 year old buck is picking his way through the raspberry canes about 15 feet away from me. I'm sitting there, trying to hold my breath, gun across my knees with a cigarette in my mouth. Luckily my hands were on the gun. When the hammer clicked back, he went into full alert, staring straight at me, like, in the eyes, at least I think he was, there was smoke blowing directly into me face. I wait, and he puts his head back down. I raise the gun, and he looks right at me again. I level the sights on tis heart, and shoot! Change my underwear and finish my smoke before my dad walks over from where he was posted while i'm lookin in the brush where the deer was. There's tracks, the big skid mark where he ran down the hill, no blood, no hair, nothin. We look around for a while, then the old man sees it. The fresh gouge in a 1/2 inch maple sapling, almost cutting it (in the front, out the side) with some lead in it, about 4 feet closer to me than the deer was. So yeah, sometimes, people hit a tree (and miss a shot at about 5 yards)
