While fish spend most of the time feeding under the water, when you can encounter them rising to take insects floating on the surface, the experience can define the essence of fly fishing. In this no-nonsense, straightforward book, Paul Weamer—who has spent his life fishing the technical dry-fly waters of Penns Creek in Pennsylvania, the Upper Delaware River in New York and Pennsylvania, and the spring creeks of Paradise Valley outside of Livingston, Montana—breaks down the best methods, rigs, and fly patterns to catch more fish.
