I'm not the only one fascinated by the old hotel . . . Historic Hotels of the Rockies is an organization of 16 Western hotels built before 1940, all now open for guests. I could just go from the Sacajawea Hotel in Three Forks, MT, to the Historic Plains Hotel in Cheyenne, WY, to the Castle Marne in Denver and on to the Hotel Alex Johnson in Rapid City, SD, and on and on. . .
