I would allocate a few Saturdays this winter/spring to drive out in the country and knock on a few doors. Nebraska too has its share of gun hunters that are giving deer hunting a bad name.

For me I take a hunting partner along for the ride. We present ourselves as bowhunter only. If you get a "No" just ask if he recommends any other farmers in the area to ask and then be on your way. If you get a "Yes" make sure you get full details of where his land begins and ends. Some hunters volunteer services to help the farmer in some way.
