After leaving Amarillo on our way to our next stop in Adrian, we passed by Cadillac Ranch, a Pop Art installation featuring ten vintage Cadillacs, upended and buried to their windshields in the ground. One of Route 66's most famous roadside attractions, Cadillac Ranch was never actually on the Mother Road. It is located in a cow pasture along I-40. Amarillo rancher and art collector, Stanley Marsh, funded three members of the San Francisco art group, Ant Farm, to create this "carscape" in 1974. Consisting of mid-twentieth century Cadillacs that were either older running cars or junked automobiles, it represented the evolution of the car line (in particular the most defining feature, the tail fins). Through the years many visitors have
spray-painted graffiti to the weather-ravaged public art installation and left with photos of their contribution to the history of Route 66.
