I got busted last season on opening Rifle day (I was carrying only my bow). I was sitting with my back against a tree in a little thicket and grunted a couple times and sure enough a nice big buck came heading in and I got so flustered and nervous(would have been my first buck with a bow) that I didnt sit up on my knees to draw back until he was about 15 yards from me and he spotted me in mid motion. I would have shot from my butt if it was at all possible but have you ever tried to shoot a bow from your butt siting against a tree? Its pretty much impossible, and needless to say he didnt hang around to let me get into position.
