This is what I've been reading lately and I've been mesmerized, barely able to put it down. If you enjoy reading any kind of history, you should get this book: The Worst Hard Time: The Untold Story of Those Who Survived the Great American Dust Bowl by Timothy Egan.
The Dust Bowl is a chapter of American history that I had known very little about. My parents lived through the Depression, but that was in the midwest, not the western Great Plains. They never spoke of immense natural disasters and incredible famine in the days when there was no government safety net to help people out of unspeakable hardships. No farm supports, no welfare, no social security. Children and the elderly dying due to dust pneumonia. Food scarcity to the point of relying upon tumbleweeds and yucca to feed your family, a mere seventy years ago, is certainly far outside any experience of my lifetime.
You think you have endurance? Try again. Read the stories of people who really did.
