There is, perhaps, no other sport in the world quite so exciting as skiing. For viewers, it is a sight of extreme beauty. For skiers, it is a vivid personal experience, a thrilling test of mind, muscle and nerves. And more and more Americans are discovering this thrill for themselves. Not too long ago, skiing had almost no part in the American sports scene. If it were thought of at all, it was purely as a European sport. Then came the 1932 Winter Olympics at Lake Placid, New York. Americans got their first good look at skiing and made for the hills. Today ski trains make regular runs from out cities to the great, white outdoors. Wood houses of various kinds dot the mountainsides offering the skiers the warmth of their firesides.
    In addition to joy and entertainment, skiing offers other attractions. It is a comparatively in- expensive sport, and for the young, the art of skiing is often learned in a very short time. The special thrill of skiing is well described by Buddy Werner. "It’s all up to you". No teammates can help. You are alone. It’s you against the snow, the mountains, the terrain, yourself. You are a warrior.
