My GPS for some reason gave up the ghost in Nebraska on the way out, but I hadn't put any routes into it in any event. I used Mapquest just to get an idea of timing, but what I did was order maps and brochures online from the various tourism bureaus in Colorado, Arizona and Utah. The maps for all of them noted scenic by-ways and honestly, by the time I got there I had studied them so often I hardly even looked at the paper maps. Then I did some wandering, just made sure I was going in the general direction of my next stop. Some of the places I wanted to see, but didn't, were the San Juan Scenic By-way in Colorado, Zion National Park in Utah, Seligman in Arizona (which is supposed to be one of the more authentic stretches of Route 66), Santa Fe in New Mexico, I had hoped to make a trip out to Las Vegas - didn't happen, I thought Tombstone was be neat as well, and maybe a sidetrip down to Roswell, NM. Guess I'll just have to go back.
