I'm still trying to figure out how it's the corns fault.[:-]

IMO a cornfield is one of the easiest places to track a deer. Blood stands out like a sore thumb. If you happen to lose a bloodtrail grid searching rows of corn is as easy as it gets. A lot easier then climbing over acres of brush and thickets anyway.
If the deer was hit in the heart and ran into the cornfield, he is dead in the cornfield.
