I live and hunt in eastern IA right along the old Mississippi river, and we have some real nice deer hunting around this area,but if you are looking for some potential record book bucks I would say any of the southern counties would be a good choice. I grew up in Wayne county which is in about the middle of the southern counties, and I have seen some monsters down there. With all the free corn and soy beans to feed on they fatten up quite nicely.
