Changes
/* Early 20th Century, WWI and the Great Depression */
As the booths descend, guests are shown dioramas which feature the latest technological advancements. Among the inventions featured are the light bulb, trolley, moving picture, and the airplane. Following these achievements, Mark Twain observes that the country was flying into the 20th century on the wings of invention and the winds of change. Because of the changes happening in the country, Twain also observes that America needed people like Teddy Roosevelt and John Muir to lead it.

At this cue, Teddy Roosevelt and Jon Muir are shown on stage standing in a forest. The two men are discussing the need for balance between industrial progress, and conservation of the environment. Muir is eventually able to impress upon the President that Roosevelt needs to stop the massive destruction of America's national parks. After Roosevelt says he agrees that they need to protect the country's resources, Muir says:
'''Once I built a tower, now it's done.'''<br>
'''Brother, can you spare a dime? ♫ '''

As the song finishes, the men discuss the state of the country, joking about how millionaires in New York are selling apples just like they are. As the storm around them begins to let up, the gas station owner hopefully suggests that Sunday drivers might now venture out for gas. In the middle of their conversation, one of the men shushes the others, so that they can listen to Franklin Delano Roosevelt being inaugurated on the radio.
