Hunting over bait is not legal in my home state,so it is not something I have to give any time thinking about.It is not something that would interest me in doing but I am not opposed to it in states where it is legal.
There are a lot of fine lines as so many others here have mentioned.It seems to me that most hunters have an easier time in justifying there method of attracting game based on how much effort was involved in creating the attractant.That makes some sense to me,working your tail off to put in a food plot,maintaining bear bait sites for many weeks while accumulating and hauling all the bait in,walking for many miles to find that grove of white oaks that is dropping big nuts.All of those things impact on me a lot differently than the open the bag of corn and dump it out kind of baiting and hunting.I would fight for your right to do it though in states where it is legal.
