I've never been to Alaska in the winter or anytime of the year and I would not want to visit or live in Alaska during the winter.
I see pictures and then look at the winter weather temperatures in Alaska and it stays below freezing most of the winter for the highs.
Denali Alaska had a -30 F for the high a few days ago and I could not imagine living there in those temperatures and the heating bill has to be huge as well.
I would hardly ever get out of my house in Alaska and I rarely get out of my house here and it's only 13 F right now.
I guess people adapt out there and bundle up and get used to it as well as the darker days and the cold weather and they use mostly heating oil to heat their homes and stay inside a lot.
Although some people have winter sports they like to do like Skiing which keeps them active in the winter in Alaska.
