Being a person who lives in an area with limited fly fishing resources , I can understand your position. I do agree that Joan Wulff's DVD is great. But if your a book worm like me , Master The Cast by George V. Roberts Jr is the best I've seen. The way it studies the mechanics that make up the cast and builds on each lesson and each technique is terrific. I do agree theres no replacement for hands on time with an instructor , but if thats not an option theres always a way to find your own instruction. Just my 2 cents.
