*Saturday Extra* At 90 years old, legendary river runner and activist Ken Sleight is the subject of a new documentary, 'The Unfinished Fight of Seldom Seen Sleight,' which premieres this weekend at Star Hall. This film focuses on his lifelong work to protect Rainbow Bridge and Glen Canyon, a place after many decades away he still calls home. We sat down with Ken and filmmaker Susette Weisheit at his Pack Creek Ranch home to talk about the film, activism, and Ken’s recipe for standing up for what’s right. Tune in.
