From the Chairman

Dear Friends of the Jackson Hole One Fly:

As some of you may have heard, the Board of the Jackson Hole One Fly recently made the difficult decision to cancel the 2020 One Fly due to the ongoing challenges presented by Covid 19. While we will miss the camaraderie of the One Fly and seeing everyone associated with the event, the decision was made based on concern for the health and well being of participants, guides, staff and everyone associated with the One Fly and the community at large. 

Although the fishing event has been cancelled, please note we will still be hosting a virtual auction on Friday September 11th (further details will be forthcoming). Please be sure to participate as there will be many great and unique items up for bid.  Your active participation in the virtual auction will allow us to continue to fund critical conservation work for which the need never goes away, pandemic or not.

We are already working on making the 2021 One Fly, our 35th tournament, the best ever and we look forward to seeing you there.  In the meantime, stay healthy.

GUIDE'S CORNER-"Six Feet of Separation"-by Zach Peyton

This term has a whole different meaning in today’s world than it did for many years in the guide community...It was symbolic, and it was the distance between the rower’s bench and the bow of the boat. We would always joke that, ideally, down the road, we would all like to move six feet forward in the boat--a metaphor for moving forward in life.
