It started with one (simple?) question, “If you only had one fly to fish for a day, what would it be?” A question originally floated to a wide audience by legendary angler Lee Wulff in a story he published in Outdoor Life . It's the fly fisher's version of "If you were stranded on a deserted island..." Let the daydreams and the arguments over the virtues of one fly over another begin. A decade or so later, in 1986, Jackson-based fly fishing guides Jack Dennis and Paul Bruun took that question and turned it into what has now become the Super Bowl of fly fishing. Or the longest-running, most hell-yes-I-want-to-be-a-part-of-that-event, fresh-water fishing competition in North America. For 38 years now, One Fly has been a weekend in September where some of the world's most passionate (crazy?) followers of the fly descend on Jackson Hole, Wyoming, to relish in the joys of competition, raise money for conservation, and build community around a shared passion.
