Whatever dude, given the chance, myself and probably everyone on this forum, would shoot that buck in a second. If its so easy why is this buck still alive? In all the years of hiking your butt off and glassing for hours have you come across an area that has an abundance of browse for the deer, a place where they feed everyday? What about bedding areas? Watering holes? If you find a place like this in the hills can the deer be patterned the same as they can in a field? As far as the corn not being there forever, forever is relative. I'm sure that corn has been there years longer than that buck and his buddies have, they know where its safe, escape routes, where to bed and get a drink, the same as mountain bucks do.
I'm curious as to what weapon you hunt with, if "the way it was a thousand years ago" is what it is about for you, I hope you have a good supply of sharp rocks.
