I've seen it for so many years that I no longer hunt in Dec. Can you kill a big one then? Sure, like any other of the 11 months of the year. But I felt my odds were greatly decreased, I screwed up with too much hunting, and I would burn myself out before the best time.
Also, I'm out everyday at 6:30am and 430pm feeding. I have yet to hear a shot that could have have been deer/coyote/hog. Only duck hunters and handgun shooters. So, it appears to be less hunting around here. Been a steady decline in hunting when the deer population crashed years ago.
