A great divide called the ocean, their kites follow different patterns, their kiting styles are different, and kit mostly different. It's hard to be sociable in the middle of the sea.
Though the only arsey buggers I ever met are the land based ones who whether they be buggiers or boarders are all some giant ongoing genital measuring competition (mostly to compensate for having real tiny ones I guess)
As for buggiers being old well the only nice kiters I meet are old guys in buggies, girls in buggies (or boards) and newbies who are happy to swap advice and get tips.
