Book excerpt: Utah's Green River is a superb guidebook that unlocks the secrets of this great river. Dennis Breer spent over 2,000 days on the Green acquiring the vast range of information shared in this book, including: Nymph fishing, dry-fly fishing, proper outfitting for the Green, float-fishing, hatches, an in-depth, year-round look at the river and its habitat, wading and floating the river, boating regs, river flows, even river-floating etiquette. And, of course, the most productive fly patterns for the Green River.
