Hi Lofty,
It does seem to be a very different sport from what it was in the early days. I think that on the whole, most people are friendly and happy to assist, but I do know what you speak of.
In the first years of kiting, if you saw a kite up across the bay, you'd drive the 25 minutes to go and see who it was and speak to them about gear and lessons learned. There was a real camaraderie in those days, perhaps it was that all of the gear was trying in earnest to kill you should you fail to pay attention for half a second, or perhaps it was just the need to find someone who cared to share stories and the stoke with.
I've saved lives of, and have had my life saved by kiters who sprinted at super human speed to intercept an out of control kite kite before getting smashed. Thanks Chris Brent, never seen a big fella move at that kind of speed before as I was planing on my belly under an unstoppable 11.8m (16m), no depower Wipika Airblast kite in an unexpected 30 knot southerly buster in Sydney. Most kiters will have to Google Wipika Airblast to understand ...
I'd like to think that there is still plenty of ALOHA, on the beaches amongst kiters.
