Reviews:
"George Daniel is destined to become one the United States' very greatest of fly-fishing talents. In my humble opinion there is no one better placed or equipped to take the modern reader into the world of the subsurface fly fisher. Daniel is one of the most authoritative and insightful anglers of his generation." --Charles Jardine

"Although he might never claim it, a compelling case can be made for George Daniel as the best fly-fisherman in the country." --Charlie Meyers, The Denver Post
