St. Vrain Anglers TU is thrilled to bring IF4 back to Longmont!
Get ready for an unforgettable night—this year’s event features the world‑class IF4 film lineup, onsite raffles, and an online silent auction packed with great gear and experiences.

We’re also shaking things up! Due to Colorado’s unpredictable spring weather, we’ve moved the event indoors to the historic Longmont Theater. Join us May 20th for an incredible evening celebrating fly fishing, conservation, and community.
