While Bud searches for his father, he comes across a Hooverville, which is a shanty town. Many of them were constructed during the Great Depression, and homes were often made of cardboard.
Bud and Bugs are searching for a place they believe to be called Hooperville. When they stop to ask about it, they are told it is Hooverville, which Bugs calls "a cardboard jungle, somewhere you can get off the train and clean up and get something to eat without the cops chasing you out of town."
Bud looks around and realizes the city is larger than he thought and splays out in every direction. It is filled with people of different races, which Bud thinks all look orange because of the light of the fire. He thinks,
They were all the colors you could think of, black, white and brown, but the fire made everyone look like they were different shades of orange. There were dark orange folks sitting next to medium orange folks sitting next to light orange folks.
The boys eat food, listen to music, help with the chores, and talk to the residents. The next morning, Bugs gets on the train, but Bud misses it. He sees the police raid Hooverville, shooting holes in the pots and pans, tearing down the dwellings, and burning things.
Hoovervilles were named after President Herbert Hoover.
