Been hunting the ski country of Western NY for thirty years. I can tell you when the food runs out, the deer leave. Deep hardwoods teaming with deer when the mast crops are dropping are devoid of deer in the middle of the winter. It is not unusual for Adirondak deer to travel 20-30 miles to yarding areas to winter. With the snow bands heavy in a narrow 12 mile swath, deer don't have to go too far to get relief. The hard thing is for the small plot hunter who has been seeing a good buck on trail camera may find his deer gone for good as the deer may find greener pastures in the move and stay.
