That was a good post.
I guess one of my questions is,
Have you found a teaching methodology yourself? (Please don't view that the wrong way. It's a genuine question because I really don't have a clue as to how one could build something like that)
If so, is it something that you can teach other teachers to use? And would a seminar be enough time?
As for the Expos. They were all West Coast. I never did understand that reasoning. If you're going to bring together that many great teachers, why not locate it centrally where everyone can reach it? If you want to reach the people, you have to be reachable.
There are a lot of Aikido people out there who can't afford to fly to California but could carpool to say St. Louis. Or have one on each coast rather than all three on one coast.
