Are you bored with your basic windsports? Grab a Kitewing, and speed along on your favorite skis, snowboard, or skates at speeds approaching 65MPH. Still too tame? Hold the wing horizontal and you'll go vertical. Just make sure to call your mom from the hospital.
Run faster, jump higher. What happens when you cross stilts and pogo sticks? The next 'extreme sport' on the verge of the big time, or a new and fun way to really injure yourself?
