Watch now (13 min) | My latest fly tying video, Last Chance Emerger, was a “years in the making” solution to a challenge I had with a particularly amazing pool in an Idaho river. My wife and I camp and fish this stream annually, in the Bitterroot mountains. The pool is a classic even flow river, loaded with fine fish, and given its features and the shallow valley it runs through, it produces insect hatches throughout the summer. What could go wrong!
