While I certainly won't say that the late season is THE time to be out there, I can say that on MANY seasons I have seen my biggest buck of the year sometime over Christmas vacation which is usually 2 to 3 weeks for us. The best buck I've got an arrow into during this time was a 150 class and a couple seasons ago we were hunting a nice 160 class 5x5 with a 10" droptine. I didn't take this buck but my huntin buddy did and it was during mid-December. I have seen a handful of true B&C deer during this time period so don't be afraid to do some sub-zero hardcore bowhuntin'. As one post above mentioned, you can't get one staying at home and every hour spent in the stand puts you that much closer to baggin' that monster buck. Once the snow stays it does tend to concentrate deer at feeding area which in my parts are always isolated cornfields. Good luck and good huntin'
