It's happened to me before. Actually, every year about the tail end of the rut though. I get does galore and a few bucks all year until about mid November. My estimation is that the property I hunt is rather small (80 acres) and thin. The 80 acres to the east of me is thick, thick, thick. There's a neighborhood to the north and about 2 miles of nothing but open cattle pasture to the south. So my assumption is that the deer are normally passing through my hunting area because it's a funnel between the neighborhood and the cattle pasture. Some food source must change about mid november and cause the deer not to be traveling this way anymore. I've learned it and become adapted to it. What size piece are you hunting, what are the food and bedding situations?
