My son also achieved a second degree black belt in a Korean martial art named tang-soo-do. That’s where my freeper name came from. Tang-soo was a form of greeting in our school. The head of our federation was C. S. Kim located in monroeville Pennsylvania. Tang-soo-do was the first style practiced by chuck norris. C S Kim was his first instructor while he was stationed in aSouth Korea as part of the USAF. The US formed an agreement for some of the military to receive training in tang-soo-do.
By the way I had to drop classes after a couple of years due to an injury. Neck and shoulder still bother me after 20 years. Good times though.
I sent you a pm. Small world, no? USAF...haven’t heard that one in a while.
Sorry about your neck and shoulder.
