On a secret hill, in a secret location, with some people who may or may not have existed I was introduced to Power Kiting. The wind was blowing a steady 20mph and the kite was a mere six meters (which I was assured was "small") Jon (possibly not his real name) turned my understanding of kite flying upside-down.
On a safety note. Jon is very experienced at kite flying so if you want to try power kiting look for a local club and DON'T try it alone.
