I have no problem with it as long as it does not go against the local hunting regulations defined by the DNR or local Fish and Wildlife Agency. The hunting purists will disagree, but to each their own.
Some of those same people that disagree with the use of corn may be the same ones using mineral blocks, deer cocaine, or planting food plots and hunting over them. This really starts splitting hairs at that point.
I bait on occasion. It is legal in my state. My time in the field is often limited and I want the best experience I can have with the time I am allotted.
I don't have a problem with it.
Fire away!
