River fever

"Beginning in the spring of 1969, Huckleberry Finn inspired a question: Could you build a raft, float down the Mississippi River to New Orleans, and on the way learn something about America and its peoples? Will Bagley, a vagrant longhair and future prize-winning western historian, and his friends could, and did. Now, a half century after the adventure, Bagley tells his story."--Provided by the publisher.
