Cadillac Ranch

Cadillac Ranch, built in 1974, is the product of eccentric helium millionaire Stanley Marsh 3 (he didn't like the Roman numeral III and found it pretentious). In collaboration with The Ant Farm, a San Francisco art collective, Marsh funded the placement of ten graffiti-covered Cadillacs half-buried in a dusty Texas field. The cars are positioned nose-down and face west "at the same angle as the Cheops' pyramids." The cars were actually moved two miles further out in 1997 to avoid the expanding city.

Visitors are strongly encouraged and Cadillac Ranch is open to the public at all hours. Graffiti on the cars is also encouraged and the cars undergo ever-mutating layers of paint. In 2005, the cars were given an all-pink makeover in tribute to breast cancer victims and later painted black and yellow to honor the passing of one of Marsh's longtime friends. While Marsh encouraged both visitors and graffiti, he did not take kindly to visitors absconding with any of the many colorful artistic road signs that dot the area. Marsh was even known to briefly jail thieves in a nearby chicken coop.

Cadillac Ranch is thought to have been the inspiration for similar art pieces, such as the nearby VW Slug Bug Ranch and Combine City. The ranch also inspired Carhenge, located in Alliance, Nebraska.
