This double-sided map covers Montana, Wyoming, Colorado, and parts of Idaho, New Mexico, and Arizona. It is, of course, the southern extension of the Canadian Rockies map through Blue Sky Montana and Mile High Denver. This is a double-sided map concentrating on roads and road quality, parks, touristic attractions, and urban areas. We feel that the state-by-state approach to mapping the USA just does not work well. With todays infrastructure and vehicular capability, one can pass through three or four states in a normal day drive.
