Book excerpt: For three years, journalist Richard Louv listened to America by going fishing with Americans. Doing what many of us dream of, he traveled from the Atlantic to the Pacific, from trout waters east and west to bass waters north and south. Fly-Fishing for Sharks is the result of his journey, a portrait of America on the water, fishing rod in hand. To explore the cultures of fishing, Louv joined a bass tournament on Lake Erie and got a casting lesson from fly-fishing legend Joan Wulff He angled with corporate executives in Montana and fly-fished for sharks in California. He spent time with fishing-boat captains in Florida, the regulars who fish New York City's Hudson River, and a river witch in Colorado. He teamed secrets of fishing and living from steelheaders in the Northwest, Bass'n Gals in Texas, and an ice-fisher in the North Woods. Along the way, he heard from one of Hemingway's sons what it was like to fish with Papa and from Robert Kennedy, Jr., how fishing changed his fife. As he describes the eccentricities, obsessions, and tribulations of dedicated anglers, he also uncovers the values that unite them. He reveals the healing qualities of fishing, how it binds the generations, how the angling business has grown, and how the future of fishing is threatened. But most of all, Fly-Fishing for Sharks is about the unforgettable characters Louv meets on the water and the stories they tell. From them, Louv learns about our changing relationship with nature, about a hidden America -- and about himself.
