Cadillac Ranch west of Amarillo, Texas Yes, Texas millionaire Stanley Marsh, 3 was eccentric. He is also said to have been very down to earth, quickly disregarding the "III” as too pretentious and using "3" instead. In 1973, Marsh invited a San Francisco artists’ collective called the Ant Farm to help him in the creation of a unique work of art for his sprawling ranch just west of Amarillo.
