lol, this thread is getting epic.
The reason kiters get so defensive when you talk to them about being a public nuisance/danger is because deep down they know that their sport is going to be banned in 90% of spots, especially as its popularity grows.
Sure there are a large majority of sensible kiters (my father in law is one of them

), but as more and more kooks, try-hards and tossers swell the kiting ranks, the inevitable is bound to happen. While windsurfing also has its fair share of kooks, etc, at least with a windsurfer, the carnage you can create is largely limited to a 430cm radius around yourself.
If kiters were smart, they wouldn't talk up their sport so much. The less people that kite, the less chance of it getting outright banned.
Kiters try to argue that windsurfing is a dying sport... I'd suggest that it is kiting which is unsustainable. Which is sad, because anything which gets the masses off the couch, away from the TV and into the fresh air is usually a Good Thing.
Just hope that windsurfing doesn't get dragged down with it.
