Hey Dave,
Once you are in Amarillo, check out the Cadillac Ranch just west of town on the south side. A Texas rancher buried 10 brand new Cadillac's in the ground at the same angle. One caddy for each year in 1950?. They are beat up now, but a good place to stretch your legs. Watch out for a million freakin' Prairie Dogs too. Cool little buggers....
ZAPCON in Mesa/Phoenix AZ in late April as a reminder....just a short jaunt.
