We haven't (yet) traveled the entire route, but, Williams, AZ is a fun stop. Purportedly the last town along the "Mother Road" bypassed by I-40 sometime in the 1985. We stayed at the KOA just outside of town. Had a great time walking around downtown. The 50s & 60s rule in Williams.
We were married in 1967 and our honeymoon consisted of driving from New Jersey to Imperial Beach, CA where I was stationed in the Navy. We traveled along the old Route 66 for part of the trip (they were building I-40 at the time). When we visited the Petrified Forest outside of Holbrook, it was along 66. We revisited the Petrified Forest 2 years ago and that section of 66 is gone. They do have a historical marker for photo ops along with the rusted out hulk of a 30 something Packard Touring Sedan.
If you stand and look at the terrain to the west, you can see the old right-of-way. Just overgrown with sage brush now. That old road is a great piece of american history.
