Rode Wisconsin to Alaske a couple of years ago. The worst roads are in NE Canada and SW Alaska. They aren't bad mostly. Just every now and again you find a spot or a good long stretch that is all tore up with pot holes from the winter. They'll have some of them fixed before you turn around and come back. They are hard to spot sometimes and that make them dangerous. I only had a hard time with them when I was really tired and thinking slow. My lesson there was stop when your tired and out in the sticks. A mile of big potholes can jump up at any time from right in the middle of a smooth road. The highway at the top of the world was packed but dusty gravel and fairly smooth. Not bad on the F6B. I had more trouble with colonel klink and his circus of exitable germans while they were on their way to cape horn than I did the highway.

Top of the world highway was gorgeous. Not as neat as rolling around in the Rockies, but well worth the time when your their.

Also don't drink with the locals in Chicken.
