RE: Deer trails?
I hunted an area like that this morning. There is a heavy trail entering a woodlot. The deer hit this woodlot on their way back to bedding in a standing corn field. Once they get about 2/3 in the woods, they reach a stand of oaks in which they feed on acorns before entering the corn.
On the topic of how fast things can change,deer will enterthis woodlot from the opposite direction once the corn is cut. They will enter the woodlot from the field that they are currently bedding in. This happens every year that field is corn. If it's standing, they enter from the north. If it's cut, they enter from the south.
