He put a rope at the front to make it easy to move. The skier called it a Snurfer. He thought of it as a snow surfboard. The idea took off. It spread more through the 1970s. More and more skiers had an interest in the sport. It was hard to find a place to go and snowboard, however. Some resorts only allowed skiing. This began to change in the 1980s.
