Cadillac Ranch, originally an eccentric roadside attraction placed by the art collective Ant Farm on the now decommissioned Route 66 it was moved and can now be found via a frontage road for I-40 just outside of Amarillo. You can see it from I-40; it will be on the southern side of the road. Park along the side of the road and walk about 100 yards to see ten old Cadillacs upended and half-buried in a cow pasture. Visitors are encouraged to spray-paint the cars; there are spray paint cans in a hole at the end of the formation. Surprisingly compelling. If you have GPS you can try using 35°11′14″N, 101°59′13.4″W to find it.
