John Clendenin, Skiing Hall of Fame honored member, is a genius on skis, as he has been since before observers of the ski scene began recording the two-time world champion’s exploits. Most geniuses can’t communicate their brilliance without abandoning, bludgeoning or boring their students. Not so, Clendenin. In “Four Words for Great Skiing,” he explains, with extraordinary empathy, the secrets to high performance skiing. His goal is to give skiers the confidence to explore “the kingdom,” the natural, ungroomed terrain where creativity and self-expression reign. His humor, his intelligence and his gift for communicating mechanics to the non-mechanical shine through every page as if it were backlit.
