I spent alot of time in Fairbanks throughout 2006 and 2008, doing aerial surveys from plane. Fairbanks was a good airport to get stuck at, and you do meet some interesting non-traditional travelers. I've never met the guy in the article, but I've met a few bike/hike travelers there who were either moving horizontally or vertically across Alaska (no small feat at all), and I always thought it sounded like an adventure.
