Actually, those aren't farm fields. That's a National Wildlife refuge. Those fields are planted for the benefit of the wildlife. They grow soybeans and corn and other crops for wildlife, and then those fields get flooded in the winter for waterfowl. The folks that plow and plant those fields are local farmers who donate their time to the refuge. A steady supply of high quality food is how they grow bears up to 880 lbs. 880 is the NC record from this region. It's not entirely uncommon to see bears pushing 700 lbs feeding near the roads.
