I've hunted over corn for years, it provides good entertainment. Michigan used to be a big baiting state, some of the outdoors stores had bins like a builder supply yard with piles of carrots and sugar beets, they would fill your truck with a loader. This farm I hunt in central Ohio has a salt pile, the deer tear the place up over that, they dug a 30' trench eating the dirt down hill from the pile. I don't see a problem with it, it will draw in some predators.
