Just a straight shot up the Dalton Hwy (AKA The Haul Road) to the Arctic Circle. Took the standard tourist photo and turned tail back, trying to beat the rain. The Dalton's mostly dirt, with some paved sections. While it's a really good dirt road, rain would have made for a lot slower, longer ride.
I would have liked to go all the way to Deadhorse, but I don't think the rear tire has enough left to get there and back and then to Anchorage, where the tires are waiting. Really don't have enough time either.
