I'm a lifelong avid fly fisherman, for in excess of 50 years now. Over that time, I have read a ton of books, attended a lot of seminars, and been taught by some of the best fishermen I know. I have NEVER read a book with this much detail! Wow. Everything one needs to start stillwater fly fishing, or to improve their skills, or even learn things I never knew is packed in here. So very, very thorough. So very well explained. The details are absolutely amazing. Fantastic diagrams, beautiful photography, it's all here folks! Do yourself a favor.....if there's one fly fishing book you're going to buy this year, make it this one. Or, maybe don't buy it, and let me keep all this great information to myself, haha! Highly recommended!
