While researching The Grapes of Wrath, Steinbeck spent two years trekking from Oklahoma to California with a group of migrant farmers. In 1960, Steinbeck set out on another trip across America -- this time with a friend. The resulting book, Travels with Charley, recounts the many fascinating people and places they encountered along the way. Who was Charley? Steinbeck's "old French gentleman poodle."
