1974:
Standing along Route 66 west of Amarillo, Texas, Cadillac Ranch was invented and built by a group of art-hippies imported from San Francisco. They called themselves The Ant Farm, and their silent partner was Amarillo billionaire Stanley Marsh 3. He wanted a piece of public art that would baffle the locals, and the hippies came up with a tribute to the evolution of the Cadillac tail fin. Ten Caddies were driven into one of Stanley Marsh 3's fields, then half-buried, nose-down, in the dirt (supposedly at the same angle as the Great Pyramid of Giza). They faced west in a line,
from the 1949 Club Sedan to the 1963 Sedan de Ville, their tail fins held high for all to see on the empty Texas panhandle.
