Hi, ID. I hope Yoshinkan is suiting you well.
A year late, but had to mention - Philadelphia is the heart of Kokikai Aikido - there is an incredible opportunity there. The founder of Kokikai, Shuji Maruyama Sensei, lives in Philadelphia three months each year, holding camps and seminars in the area, and leading regular classes as well. This makes for ...significant local instructors.
Kokikai does not consider itself a subset of Ki Society. (We're encouraged to avoid the word "ki" - Maruyama Sensei tells us it is too much potentially confusing.) The Kokikai Basic Principles are not the same as Ki Society's.
FYI see
www.kokikai.org - of course it can't begin to address your questions, but - YOW - Philadelphia! - I just got back from our advanced seminar week there - I'm kinda jealous, you _live_ there! No, training in Boston is ideal for me, but I try to spend as much time in P as I can when Sensei is in town.
(There's some devastating ukemi available for enthusiasts!)
