This monument, located along the old Rt. 66 outside of Amarillo, has become an effigy to the fabled route through the Southwest and the spirit of the American road trip. Ten Cadillacs buried hood first in a field are an art installation and an homage to the evolution of the Cadillac tail fin on car models ranging from 1948-63. A popular tradition to tag (spray paint) something onto the carcasses is a right of passage for travellers of the Mother Road. The paint is inches thick, and gives the car frames a cartoon-like bulbous appearance. Many people leave cans of spray paint for others to use, but please do not leave empty cans of spray paint or trash here. In 1997 the cars were dug up and moved to their current location to escape the expanding city limits of Amarillo.
