All depends on how you are dressed I suppose. It's been single digits up here all week and I've not missed a bowl or cigarette when working outside or exercising the pup. Ahh, but then there is the wind! Wind can send me into the truck and sometimes home to smoke. Below zero temps and wind make it waaaay below zero, then it's a bowl or two by the fire with a hot chocolate or, later in the day, say 0930 or so, a bit of Port.
