Around where I live, the public land hunters rarely go deep. Obviously you need to do your homework and locate bedding and feeding areas, but if it was me I'd go as deep as you can and locate some where there isn't much pressure. I knew one guy that actually kept an old beat up 4wheeler about a mile and a half back in the woods. He would walk in real early, and get on his bike and drive for about an hour more back in. He killed some real nice deer, and never ever saw another hunter.
