Go read what the DNR calls a "legal" dove field. They establish several around the state every year with state money. It is baiting, plain and simple, and very easy to do if you get to spend other people's money to do it.
Deer "food plots" are the very same thing.
Yeah... I really haven't heard a good argument on why one is "bad" and the other is "good". IMHO: If you don't like it, don't do it....
