Hunt the fronts.
Cold fronts seem to affect Deer movement more in the late season than at any other time in my experience.

Deer will really be up and feeding heavy a few days prior to the arrival of a cold front and the days following a cold front. Usually the day before will be the most active.  It seems the level of activity is also dictated by how severe the front is.
If the barometric pressure is moving, so are the deer.
