The Jackson Hole Mountain Festival romps Labor Day Weekend with four days of music, food, arts, movies, and sales, all taking place in Teton Village. There's even a fishing derby. Outdoor music concerts headline Matisyahu who fuses orthodox Judaism with classic reggae and Grammy award winners Los Lonely Boys, Aug. 31-Sept. 3. Indoor music changes nightly with bands in the Mangy Moose. A free outdoor showing of the movie ET kicks off the weekend. The festival is also the time to pick up deals on skis, boards, outerwear, and accessories. All Teton Village ski and snowboard shops — Jackson Hole Sports, Teton Village Sports, Wildernest Sports, Jack Dennis Outdoor Shop, and Pepi Stiegler's Sports — plan to celebrate the long weekend with ski and snowboard gear sales.
