My Dad had a botched surgery 2 years ago and is left numb in the backs of his legs and the bottom of his feet. He has very little balance. Anything I can do to keep him in the sport I'll do. He can't cant stand up and turn around to shoot a deer like you and I, so in my case it's 100% justifiable. I don't hunt over bait 100% of the time actually I don't more often than not. If he could walk as good as I could I'd probably only buy 1/3 of that to help concentrate the does pre-rut through rut.

Edit: Where I hunt there is a bait pile around every corner, MOST everybody baits.
