I used to live in Arizona and have seen Sedona, Flagstaff, etc. Of course it would be fun to do that again, but I decided to route through Prescott/Pine/Strawberry instead just as a personal preference. Those are really pretty areas with not so much tourism.
A tentative return leg has been added to the first post. So far its highlights are Santa Fe, a bit of Utah and the North rim of the Grand Canyon.
