I met Master Kim when I was stationed at Osan AB back in 1969-70. I took a couple of lessons but didn’t have the drive to keep it up. Can’t remember but I think that the lessons were either free or cost very little. I’m still kicking myself for not keeping up with it.
Wow that’s awesome. I will share this with my son. Oh and I just remembered two other instructors. Joseph Goss senior and junior. They run a successful school in johnstown PA.
