I am so very happy they are bringing Mr. Wallis on board. Route 66 has a fantastic history in this country and in California. The film Cars did so much to bring attention to the often forgotten part of history and the "Mother Road" herself. This news is bringing joy to me and I cannot wait to see what WDI will do when they bring "Radiator Springs" to life. I am so excited! Bravo Mr. Lassetter, thank you for bringing back the "Magic" into the kingdom.
I think that the person that dissected the information from that book and then felt the town was a bit confused because Kingsman is nowhere near new Mexico.
Kingsman is near the border of California and Arizona west of flagstaff.
That would also explain some of the background scenery that is found in Needles California as well as the background that has influences from the Grand canyon.
I could have sworn I read somewhere that the concept of the story of Radiator Springs was based on Amboy, California, one of those small towns on Route 66 that was bypassed by I 40.
The scenery is a different story. It seems to be a mishmash of Arizona, New Mexico and Utah.
