Cheyenne 1935

The U.S. Post Office gave Cheyenne's aviation its first boost. With the introduction of airmail routes after World War I, Cheyenne civic leaders lobbied to establish Cheyenne as a stop. By the latter 1920s, Cheyenne had become an important crossroads for mail and passenger flights on a transcontinental route between San Francisco and New York as well as a north–south route from Cheyenne to Pueblo, Colorado.
