Quite so.
In the meantime, having looked at a TWA Lindbergh Line map, I wondered what had become of Winslow Arizona (apart from the Eagles song) featured large on the transcontinental trunk route and just up the road from OP's challenge. Seems it used to be the most important town in N.Arizona & a rail hub until the Route 66 bypass cut it off and now has a population less than 10k. Just like Radiator Springs In "'Cars"....
