An acquaintance (not me) flat out hunts over corn, he'll run his ATV up to a spot 30-40 yards from a stand and put out 100-150 lbs of corn 4-5 days before a hunt. 4 or 5 times a year. He's had some shooter bucks he's taken that way. Doesn't seem to care that it's illegal.
I've seen pictures he's taken from the stand of 6-7 does around the line of corn.

I hunted over a red mineral block that was covered in peanut butter once. Watching a raccoon lick the whole thing clean of peanut butter in 10 minutes was the lesson I needed.
