S1 E1 • Cruncher

Jack Webb's latest effort turns to park rangers filmed at Yosemite National Park, offering the viewer a mix between the Emergency formula and the Disney hour, introducing Cruncher, the bear, a personality with food on his mind. Rangers rescue mountain climbers and settle disputes between campers as Cruncher pops in-and-out of the action, raising cain and foraging among garbage cans. The handsome Yosemite location footage is the best thing about the show.
