Speaking as a second generation in law of the UP, it is either a near paradise on earth, or hell during a cold spell. I have been there during rifle deer season {last half of November} and experienced minus twenty to sixty-five. No snow, to snow so deep my hunting partner, who is a lot tougher than I, turned around at the entrance to our drive and drove right back home to Illinois. It is beautiful, and really great all year around if you are not too far back in the brush. I would have tried to convince my wife to move up there when I retired, but help can be a long way away if you have a medical emergency. I think she was influenced by her mother's stories about walking across Little Bay de Noc on the ice to sell butter and eggs in Escanaba.
