1999 Studio "B" San Pedro YMCA:  Supreme Grandmaster Nam Suk Lee accepted Grandmaster Jon Wiedenman and Master George Fullerton's requests to come out of retirement and teach at the San Pedro YMCA Dojang, which was Grandmaster Wiedenman's main dojang (Studio) at the time.  This is the historic location where Supreme Grandmaster Lee would teach both his group classes and his privates.  He was also a member of the YMCA, here.  It is often acknowledged as a very significant Chang Moo Kwan cycle, Supreme Grandmaster Nam Suk Lee both started and ended his Chang Moo Kwan teaching at YMCAs.  The first in Seoul, Korea, in 1948 with Grandmaster Byung In Yoon, and the at the end with Grandmaster Jon Wiedenman at the San Pedro YMCA.
