We stop for a couple of days in Santa Fe, New Mexico. I always find it beneficial to take a rest day after doing 1,200 miles or so in a couple of days. No sense in making a death march out of it. Besides, loads of great restaurants and things to do in Santa Fe. Great place. Took a quick cruise to Los Alamos... And past the Valles Caldera (see: http://wikitravel.org/en/Valles_Caldera_National_Preserve ), it's a rather large volcanic hole - a blowout like Mt. St. Helens only larger.
