It's called localism and it comes from being repeatedly screwed by some knob from somewhere that has even more severe localism than your patch. If you live near this spot it's your duty to give them a hard time. They expect it.
So if I see 5 or so guys setting up old warroos at the edge of the pond I know its time to get out and get my deck chair, phone and popcorn. Kite wars, imagine the carnage and imagine the number of YouTube hits. Now that would be something to see. On a more realistic note ( sorry I got carried away with how awesome that would be),
Yes you need to act as a collective for sure and it does need some coordination. This may prevent physical violence which lets face it is not what anyone wants. Like a one night stand with your sisters best friend, good at the time but after....
Damn I do like the idea of an armada of kamikaze kites from 2006 just crashing through the line up. Might add another aspect to the sport, smash em up kite sessions. Ooh yeh.
But maybe the pond has not critical mass and cannot be fixed, don't know.
Localism does achieve what it sets out to do. There are surf beaches around Aus where nobody would dare snake or drop in on anyone, and there are places like Bondi where there is no real localism anymore and people do what ever the hell they like (also it's a very popular beginners beach). Most of this from word of mouth.
But it sucks when the pendulum swings too far, and suddenly locals decide they have the right to then ignore the rules when it comes to visitors. I've been at beaches on road trips where I have been ID'd as a tourist (kinda obvious) in the lineup, and you get treated like absolute **.
