Who was your teacher during that time frame? I studied under Mr. Chung during the late 60's and 70's. He is who told me that he trained under GM Oh. I trained in the late 60's in Joe Corley's Smyrna school mostly under Charles Henry. When Charles left Joe's employ, he sent me to see Mr. Chung.
Cool to see somebody else from ATL from HSC's line. I studied at Lockheed karate club from 81 to about 90/91 & we were supposed to come from that school.
