Don't worry! I get being a newbie to some of this stuff. People ask me to describe what Mike and Dan and Akuzawa do...yeah right! I make a few fumbling attempts, and then give up.
But the Sanchin kata is actually something I can look up and then try to apply the principles I see Akuzawa and others using. Then maybe I can find out how far off base I am if I get my butt up there in October!
