In this episode of the Radio Hour we turn back time fifty years to the debut of Walt Disney World's Tomorrowland expansion of 1975! We take a look at the development of its three signature attractions - Space Mountain, the WEDway PeopleMover, and the Carousel of Progress. We also revisit a rather unusual television special meant to promote the arrival of Florida's First Mountain™. Now is the time, now is the best time, it's the Progress City Radio Hour!
