Cadillac Ranch...

"The Cadillac Ranch, located along the tatters of historic Route 66, was built in 1974, brainchild of Stanley Marsh 3, the helium millionaire who owns the dusty wheat field where it stands. Marsh and The Ant Farm, a San Francisco art collective, assembled used Cadillacs representing the "Golden Age" of American Automobiles (1949 through 1963). The ten graffiti-covered cars are half-buried, nose-down, facing west "at the same angle as the Cheops' pyramids."
