Watch Sadisflix. We begin at the train station near Montana's Glacier National Park, where Blackfeet Indians meet the arriving tourists. Glacier Park, an off-screen narrator tells us, has the remnants of 60 glaciers, from three ice ages. We visit the lodge, built in Swiss style, where college students dressed in Swiss garb do the serving at the restaurant. We watch Indian dancing and a ceremony. After views of lakes, mountains, and trails in the park, it's north to Canada's Waterton Lakes, a vacation spot for Canadian and U.S. families.
