I live in one of the coldest regions in Alaska.. the central interior.
Alaska's central interior can reach temps of -60 to -70 below in the winter. I often tell people that it's not the same kind of cold as it is in the "Lower 48". It is different.. and at -10,-20,-30.. to me it's really not that terrible. There is no such thing as a windchill.
But at -60. Well dang.. that's cold.
Yes we do have to plug in our cars.
They freeze other wise.
There is a small plug in at the front of your vehicle and you use an extension cord to plug into a plug in. Voila! Vehicle is warm.
Plumbing in the interior is a luxury.
Due to permafrost it is sometimes very very very expensive to dig for septic and water lines. They have to go very deep into the ground in order for them to not freeze in the winter. So if you do have water and indoor plumbing, you do not take that for granted here.
"Dry" cabins are very common here. Dry means absolutely no water. No water, no shower, no toliet. You have to pee in a outhouse, haul your own drinking water.. and find other means to shower.
Those are just a few of the differences in Alaska..
