Hello, I've been winter trail riding for 15 years, mostly in the Fairbanks area. I've got a non-commercial website devoted to winter mtn biking (some summer too) in Alaska. Trails, trips, over 150 photos many of which are part of the trip pages. It's produced good feedback and I hope some on the list will find it of interest.

On the main page is a link to my yahoo photo album, over 160 photos and steadily growing. If anyone is coming to the Fairbanks area feel free to contact me for trail or other information. tony
