A particularly poignant image from Dorothea Lange:
August 1936. "Example of self-resettlement in California. Oklahoma farm family on highway between Blythe and Indio. Forced by the drought of 1936 to abandon their farm, they set out with their children to drive to California. Picking cotton in Arizona for a day or two at a time gave them enough for food and gas to continue. On this day they were within a day's travel of their destination, Bakersfield. Their car had broken down en route and was abandoned."
