RobA, expect the bucks to drop antlers early this year, especially if it gets cold and snowy early. With the dismal acorn crop, the deer are hurting this fall. I've seen bucks lose their antlers during PA's firearms season which is early December generally and I have seen PA bucks with their antlers on at Easter. But as esshup said, 80-90%+ will lose their antlers between Jan and March.
