Few activities offer the sport and serenity of fishing. That unlikely combination has made fishing a popular pastime for people of all ages and backgrounds. Presidents Jimmy Carter and Herbert Hoover did it. So did literary giant Ernest Hemingway. Fly fishing elevates this rather humble sport to a true art form. A fly fisherman must develop a rhythm and style for his cast, and then practice unending patience. That's why Izaac Walton called fly fishing "The Contemplative Man's Recreation."
