The American Museum of Fly Fishing has funded a film titled "Why Fly Fishing" that features angling giants such as Joan Wulff, John Gierach, and my personal favorite, Flip Pallot from the Walker Cay Chronicles (nobody in fly fishing can match his beard). I haven't seen it yet, but the folks at Midcurrent go so far as to call it inspiring (and I don't believe they were talking about Pallot's beard, although you couldn't blame them if they were).
You can see a clip here. If you like that, you can buy a copy from the Book Mailer. Enjoy.
