The property line runs along the two roads on the west and south. The line to the north runs along a ditch that runs along the tree line in the corn field. However, there is a new access road along the tree line in the corn field. The two access points are in orange. The small orange line is an access point, but requirers crossing a deep ditch. I have no idea how far the east boundary goes. 

Looking north: They were building the access road the day we were there.

Looking north and the access point.

Looking west, the pond.
