Lots of discussion on rec.windsurfing about this. apparently, too many bozos were straying directly into the flight path instead of staying in the permitted area which was closer than the 5 mile general prohibition. Several times the tower has had to halt operations until the kiters were out of the way.

The concern is that a crippled jet sucks in a kite as it's laboring off the runway on a single engine. Seagulls are bad enough but a kiter? Oops, meant kite. The locals are talking of hiring a park warden in an effort to police the area on a full time basis.
