I never could undertand why any farmer/rancher that had crops in the field would not allow ethical hunters to not harvest some of the game off their property.

The problem we had in this state was when we did allow hunters on the property, they left gates open or broke fences, some marched right through the fields over the corn knocking the stalks down, and then wondered why they were kicked off the land. So I never totally blame the farmers. Some of them have had some rather bad experiences with hunters.
