In 1974, members of the Ant Farm group from San Francisco west of Amarillo buried ten Cadillacs in a line and at the same angle as the front half in the bottom of a corn field. They date from the years of construction 1948 to 1963 and represent the beginning and the decline of the tail fin models of the 1950s. The angle at which the vehicles are buried is said to correspond to the slope angle of the pyramids of Giza. They symbolize the freedom that the automobile brought with it, and at the same time the fascination and attraction that emanates from the “roadside attractions” along the American highways.
