During the Dust Bowl of the 1930s, millions of desperate Americans abandoned their homes, farms and businesses. It was one of the largest migrations in US history. In the 1940s, Pat Rush’s family were farm laborers, exhausted by trying to make ends meet. So they left Arkansas and followed the hundreds of thousands who had traveled Route 66 to California. There, the federal government had built resettlement camps to help deal with the influx. Migrant stories have two parts: the leaving of an old life, and the building of a new one.
