Legally, baiting may be illegal in your AO while food plots may be legal.
Morally, they seem to be designed to do the exact same thing.
Concentrating deer with an artificially supplied food source, be it a food plot or bagged corn, is something every hunter has to reconcile for themselves.
Personally, I have little interest in shooting a deer over a purpose built 'food plot' and even less interest in shooting a deer with its head in a bucket of grain. Both feel like baiting to me. Obviously, my opinion is in the small minority. If corn baiting is illegal, inform the warden of your suspicions.
