Kitesurfing

There seems to be a new sport popping up on the beaches of Hilton Head - Kitesurfing. Have you seen this, it is awesome to watch. Surfers stand on their small surfboard and a big kite catches the wind and powers them across the water. They can jump and do acrobatics. It is fun to watch in the late afternoon on North Forest Beach. They follow the wind down the beach, but I can't figure out how they get back...
