About the book (from Wikipedia):
Travels with Charley: In Search of America is a travelogue written by American author John Steinbeck. It depicts a 1960 road trip around the United States made by Steinbeck, in the company of his standard poodle, Charley. Steinbeck wrote that he was moved by a desire to see his country on a personal level, since he made his living writing about it. He wrote of having many questions going into his journey, the main one being, “What are Americans like today?” However, he found that he had concerns about much of the “new America” he witnessed.
Steinbeck tells of traveling throughout the United States in a specially made camper he named Rocinante, after Don Quixote’s horse. His travels start in Long Island, New York, and roughly follow the outer border of the United States, from Maine to the Pacific Northwest, down into his native Salinas Valley in California, across to Texas, up through the Deep South, and then back to New York. Such a trip encompasses nearly 10,000 miles.
