Marc Johnson with
http://floridakiteboarding.info/ just told me about this clip. Stay out of squalls or else, ka-boom!
To my knowledge no kiters have been struck by lightning yet, pretty amazing considering how hard some of us try. It may well come someday. The squalls that toss out lightning have taken many dozens of kiters and likely injured hundreds worldwide through excessive winds however.
Avoiding a lightning strike only makes good sense. So does avoiding squall winds, some folks get it and some don't.
