The highway was first opened in 1928, although much of the route was not paved for decades afterwards. It soon captured America's imagination. John Steinbeck, in his 1940 novel Grapes of Wrath, chronicled the migration along Route 66 of thousands of farmers leaving the Dust Bowl of Kansas and Oklahoma during the Great Depression, trying to reach a better land in California. Steinbeck posited the road as an almost hostile force, draining money, energy, and enthusiasm from the optimistic Okies.
