Why shouldn't you kite-surf in tropical storms? Because they'll f*** you up. Not only will they slam you into the beach, they'll fling you across the street and into a concrete wall for good measure. Now I hate to say this is Darwinism at work, but I will mention the Saber-Toothed Tiger was notorious for freaking around in tropical storms. Coincidence?
Thanks to Julian, who could actually throw you that far.
