Actually, I first heard about “Jail House Rock” martial science in the late 1960’s and there was an article in Black Belt I believe in the 1970’s. I am interested because of the different ranges and practicality. However, exchanging knowledge with someone skilled at this science may be problematic to say the least.

This continues to evolve as the years go on.
