Hi Adrian, I have spent time up there, albeit long ago, and have similar experience. The points you bring up are absolutely correct. When it's -30 out there, 45 feels pretty good inside, and we do bundle up in doors. I noticed the same thing about her. Also, your idea of a wind generator is a great idea. We did not have efficient ones then, when I was there, but this would definitely keep some lights on, as well as run a little electric heat to help out. Thanks for your post!
