Welcome--love to have a far norhterner on the site! But that last frontier is a big place--what part are you in? My only trip to AK was in December, so I didn't get to see much singletrack, but I know it's up there. Be sure to clue us in as to what you find.
I hope to get out to AK one day. Its one place I've always wanted to go and I would love to hit some single track out there! Ive watched videos where guys take bush plains out, get dropped off and take epic couple day bike trips back to there car. Looks sick! Hope your rides go well!
