Hunting over a corn pile is illegal here in VA, but hunting over a corn field or soy bean field is not. I don't see a whole lot of difference between the two.

Also, in some southern parts of VA, you have people running deer with dogs, running all over other people's land, driving like a bat out of heck down roads with houses and kids around to get in front of the dogs, taking running shots with buck shot at questionable distances, etc. etc. Personally I'd rather see them hunt over a corn pile.

Just because it makes it easier doesn't make it unethical. Hunting over a corn field is often easier than hunting a densely wooded area, does that mean it is unethical? Hunting with a rifle is easier than hunting with a bow, and hunting with a compound bow is easier than hunting with a recurve. There are plenty of places where you can shoot a deer over a corn field any day of the week, and there are other places where you can lay a corn pile and only see one deer the entire season.

My buddy in SC baits where it is legal. After several years, I am still the only person to harvest a deer on that land. The deer there are nearly completely nocturnal.

It isn't a question of ethics. As long as you are safe and respectful and enjoy getting out in the woods, I have no problem with that.
