Another Way to Commute

This isn't strickly cycling, but I thought it was an interesting alternative commuting idea.  David Grimes, an IT manager across the pond from us, avoids rush hour traffic by kite-surfing to work.  If I've done the math correctly, it looks like he travels about 10 miles, it certainly is tempting to think about.  I'll have to keep an eye on the prevailing winds and see whether they would be in my favor to every attempt something like this.  I certainly have the water access, but I'd be traveling in a fairly major shipping lane.  I'm just not sure I want to tangle with the ferries and cargo ships.  I'd also have to spend some serious time practicing, certainly wouldn't want to get tired out at about the half way point!
