From his blog...

But I also wanted to use it as an excuse to speak again about kitesurfing. To me it's the best sport in the world. You can start at eight and keep at it until 80. It's not as expensive as you might think. You find friends to teach you and it doesn't take more than four hours to be up and away. You can share you kites with friends too.So you just need to be able to get to a good lake or beach with good winds and you can embark on one of the most addictive, clean and enjoyable pastimes of your life.
