I was visiting friends in Saskatchewan, Canada over Christmas and the weather was -30F with wind chill made it -41F
I was raised in Saskatchewan.
Hey, me too, Sask and Manitoba. We had about 2 weeks here of weather like that, a balmy -16C today. I get a kick when I watch the news and its -5C in somewhere like Toronto and they have these big parkas on and actually think thats cold. You get used to it.
I used to be in an Army Unit and for two years we would go to Norway for Jan, Feb and Mar, this was for Arctic survival training followed by an exercise above the Arctic Circle. Whilst this was cold, it was a dry cold and because you were very active you stayed warm, it was only when you stopped that some suffered. They were wearing too much clothing, overheated and sweated heavily, when we stopped they started to vet very cold because of the sweat.
My second year, I started of doing the Arctic Survival Instructors course and that was pretty cold. I then went back south to run the units basic Arctic. This was unseasonably warm and at times was even above 0
oC and made everything, skiing, building snow shelters very difficult.
I have never really had a problem with the cold, working on the principle you can always get warm. On the other hand, working in hot climates is much harder as it is tough to cool down.
