Welcome to another edition of our weekly trivia challenge, in which we test your knowledge of all things fly fishing and where you might learn a thing or two about this sport we love. This week, we’ve got a classic quiz that covers subject as diverse as fly casting, geography, and famous fly tiers.

The last quiz was apparently another toughie, as just one person– Clint Brumitt–achieved perfection, “by getting a couple of lucky guesses.” One other person claimed a 100%, but followed that up with “easy enough, just a couple searches,” whic is not good cricket. Three people scored 9s%, and the most common score tumbled to a 50%.

The winner of this week’s random drawing will receive a a copy of Dave Karczynski’s wonderful new book Orvis From Lure to Fly: Fly Fishing for Spinning and Baitcast Anglers. Karczynski helps conventional-tackle anglers translate and transfer their existing knowledge base and skill set as he introduces and reinforces core fly fishing concepts.

The winner of our last quiz (as determined by random.org), and recipient of Dave Hughes’s new Essential Trout Flies: 50 Indispensable Patterns with Step-by-Step Instructions for 300 Most Useful Variations , was Bill, who declared “60% and proud of it.”

So post your score below for a chance to win a great book.

Good luck!
