"One of the best acid tests of an introductory book...is that the text allow the reader to learn an important skill independent of the illustrations. Fly casting is very difficult to teach in person, and even more so in print, yet this book contains the best, the most interesting, and the most effective introduction to fly casting I have ever read. I think Terry puts the emphasis in the right places...he doesn't neglect entomology, but he devotes twice as many words to trout behavior, a far more interesting and useful pastime if you must introduce a scientific bent into your fishing. If this is your first fly fishing book, you are very fortunate, you're starting off on the right track. If you've read others before, I think you'll agree with me that you wish this had been your first." --Tom Rosenbauer.
