Why did so many of the refugees pin their hopes for a better life on California? One reason was that the state's mild climate allowed for a long growing season and a diversity of crops with staggered planting and harvesting cycles. For people whose lives had revolved around farming, this seemed like an ideal place to look for work. Popular songs and stories, circulating in oral tradition for decades (for more on this topic see "
The Recording of Folk Music in Northern California" by Sidney Robertson Cowell), exaggerated these attributes, depicting California as a veritable promised land. In addition, flyers advertising a need for farm workers in the Southwest were distributed in areas hard hit by unemployment. An example of such a flyer, publicizing a need for cotton pickers in Arizona, is contained in Charles Todd's
scrapbook. Finally, the country's major east-west thoroughfare, U.S. Highway 66 -- also known as "Route 66," "The Mother Road," "The Main Street of America," and "Will Rogers Highway" -- abetted the westward flight of the migrants. A trip of such length was not undertaken lightly in this pre-interstate era, and Highway 66 provided a direct route from the Dust Bowl region to an area just south of the Central Valley of California.
