Very few mature bucks are killed over a bait pile! The problem with baiting is that it makes deer lazy and even more nocturnal than they normally are because they know right where they can go for a quick meal without having to get up before dark. A smarter old buck normally won't come into a bait pile unless does are coming in season and then it's for that and not to eat. The only time I've hunted with that method is with corn spin feeders down in the thick brush country of south Texas where you need to draw deer out of the heavy cover onto a sendero or small open area to even see them.
