<P> In golf, the terrain on golf courses is often made more rugged and hilly to make the holes harder to play . For example, the hole may be located at the top of a hill, and the course is designed specifically to make it almost impossible to allow the golf ball to rest near the top; it would roll down, and the player would have to try again . </P> <P> Cheese rolling is an annual event in the West Country of England which involves rolling a wheel of cheese down a hill . Contestants stand at the top and chase the wheel of cheese to the bottom . The winner, the one who catches the cheese, gets to keep the wheel of cheese as a prize . </P> <Ul> <Li> Sophienhöhe, Germany (200 m) </Li> <Li> Kvarntorpshogen, Sweden (100 m) </Li> <Li> Expedition Everest (61 m (200 ft)) </Li> <Li> Blackstrap Ski Hill (45 m (148 ft)) </Li> <Li> Silbury Hill (40 m (130 ft)) </Li> <Li> Grizzly Peak (Disneyland Resort) (34 m (112 ft)) </Li> <Li> Mount Manisty (100 ft) </Li> <Li> Monks Mound (30 m (98 ft)) </Li> <Li> Mount Gushmore (27 m (89 ft)) </Li> </Ul> <Li> Sophienhöhe, Germany (200 m) </Li>
