Life at the Flying U Ranch in the Bear Paw country of Montana was pleasant. Andy, Pink, Slim, Big Medicine, Happy Jack, and the other members of the Happy Family. Here they must confront defiant sheepherders just when Chip and the Old Man are in Chicago. Bower delights in showing how they deal with rage and frustration without resorting to violence. The witty and nervy Flying U bunch gets satisfaction from a difficult situation justly ended.
