Today I went and met with the unicycle hockey group in Hong Kong. They meet every Monday evening at North Point on an outdoor court to play hockey while seated on unicycles. It is really fun. We played about 5 against 5 and it took us 2 hours to get a 11 to 10 win. Almost every time I hit the ball I fell off the unicycle. But is so much fun.
If you ever come to Hong Kong drop by and have fun. Here is the website that contains also other information about unicycling: http://www.unihk.org/
