I have been reading books about the Great Depression for years. I originally started to learn some of the money saving tips used during that time, but soon came to be fascinated by the history itself.
An environmental disaster, called the Dust Bowl, hit the High Plains of the United States during the Depression. This book describes the lives of the people that remained on the plains during the "dirty thirties"; their innovation and bravery.
So please pick up a copy of The Worst Hard Time by Timothy Egan. It is definitely a good read.
