We'll be driving from Chicago to Tucson this summer, spending a chunk of time in Colorado along the way. We'll either cross into CO on I-70 in Colorado Springs or on I-50 into Pueblo. We'll be heading to Gunnison, then south on 550 to Ouray and Durango before heading west into AZ.
In AZ we want to visit Canyon de Chelly then will probably stop in either Holbrook or Winslow before heading back to Tucson.
Any help along these routes would be most appreciated!! We're looking mostly for "road food" ...diners and interesting local places. However, if there are particulary special mid-to-upper range places, please do mention them!
