The rut is the same time every year give or take a few days. Amount of light entering the does eye triggers her into estrous. This yrs rut is particularly good. New moon, cool temps and lots of snow have contributed to alot of big deer being shot already. Anywhere between the 10th and 20th, in my mind, are the best dates to be afield if you are after the big fellas. Got a dandy on the 14th. He was a 4+4 that went 168. If I could figure out how to post a pic I would. Good luck you all.
