I took the job.
Will be moving to Fairbanks mid September. I'm looking forward to it.
Regarding the long dark winters, all of the locals I talked to told me you need to have at least a weeks vacation to someplace with sunlight mid-winter and that helps you make it through. I get the impression that it's not so much the cold that depresses people in the winter, but the darkness.
its a mixture of both. But as long as you stay active you'll be fine. And if you do start getting restless, take a weekend down in Anchorage or anywhere in the Mat-Su valley, its really nice down there.
And whenever you move in, send me a PM! I'll have to buy you a beer before i leave in October!
