Thanks for the invite and I am sorry I could not make it. I would love to hear more about the New York Seminar. I am going to try like heck to make that one
If you get a chance perhaps you could write an "after action report"
Ushiro Shihan along with Nishio Shihan are two folks whose "Internal Power" I have personally experianced. Heck just the other night I was showing some folks a few "internal power punch" Atemi for Iriminage.
I hope you get a chance to share your experiances with us.
