This booklet argues that “scenic Colorado” is the best answer to the above question (which is posed on the front cover, while the cover shown below is, like Rock Island timetables, on the back). It also notes that “The Rock Island is the only road operating separate direct lines and independent through service to both Colorado Springs and Denver–the two gateways through which all Rocky Mountain travelers must pass.”

The booklet, with black-and-white photos and blue highlights, is nowhere near as appealing as The Garden of Allah, the advertisement for Arizona and California that Rock Island had issued just a few years before. It was also something of a comedown from the various editions of Under the Turquoise Sky that Rock Island had issued over the years, including one just three years before this one. But it must have been persuasive, as someone wrote “place we must go” on the above cover.
