I have been hunting the last 6 years, and I have used corn as bait everyone of those six years. I hunt in NC so it is legal. I dont see a problem with using a bait pile. To me it gives the hunter more opprutunity to take an ethical shot. I dont know how many stories ive read on here about losing deer due to bad shot angle. Most of the time with bait piles deer will hang around longer and possibly give the hunter a better shot.
I also wanted to point out that I grow the corn I use for bait, so how is that easier than hunting a food plot. I have to put in the same amount of work, if not more, to use the corn as bait.
I ultimately feel that if it is legal to bait and you want to do it, you shouldnt be condemned for it. I also think that it doesnt take anything away from the deer you do kill. Using baits, you still have to know where the deer are and you still have to make a lethal shot.
