William Least Heat-Moon

Writer William Least Heat Moon. His 1983 chronicle of traveling the back roads of America, "Blue Highways," became a literary classic and a huge best-seller. In his new book, "PrairyErth," Least Heat Moon looks at the geography, geology, and history of one county in Kansas. (The book's published by Houghton Mifflin, and "PrairyErth" is the correct spelling. There's no second "a").
