Here's a fun fact (thanks, Wiki): "The Weedpatch Camp (also known as the Arvin Federal Government Camp and the Sunset Labor Camp) now on the National Register of Historic Places, was built in 1936 south of Bakersfield, California, not by the RA but the Works Progress Administration. The camp inspired John Steinbeck's 1939 novel, The Grapes of Wrath, and a 1940 film adaptation directed by John Ford.
