Cadillac Ranch, located just outside of Amarillo, was the brainchild of Stanley Marsh 3 (the third) in 1974.
Stanley Marsh made is fortune from helium and the he ten graffiti-covered cadillacs are half-buried, nose-down, facing west "at the same angle as the Cheops' pyramids."
It's a very bizarre thing to have in a corner of a field. People are allowed in the field 24/7 and are encouraged to spraypaint the cars as much as they like.
We forgot our paint on this occasion.
