Hey oldxtreme . . . interested to hear your thoughts after comparing the two routes. I've done Beartooth Pass (and nearby Chief Joseph) several times in both directions but have not yet had the time or opportunity to travel on the B as far east as Tennessee. While I'm sure both are amazing roads for their own set of reasons, how would you personally compare them from a pure riding perspective? One road 'funner' or more 'challenging' than the other? Just curious until I have the good fortune to ride east and discover for myself!
