Somewhere out on I-40 you'll find the famed Cadillac Ranch.  It is quite the site to see and has changed a lot since it was created in 1974 by Ant Farm.  Aliens moved the monument closer to I-40 in 1997.

I just don't have the time to get out there like I used to.  When I get to missing my friends at the Ranch I quench my thirst for buried cars online.

Here's a free video tour of the Cadillac Ranch.  It's a BBC production but the host is pretty easy to comprehend.  Hopefully these guys made it back across the pond.
