I take Tae Kown Do and have done it for 3 years. It is fun for me and was worth the 3 years of training. Through all the belts, white, yellow, green strip, green, blue strip, blue, red stripe, red, black stripe, double black stripe, and finally, black belt. I meet many friends and different trainers. Many of the trainers came from the Korean Tae Kown Do school. They are old but can kill you with a single kick! Would Tae Kown Do be know as a another hobby? I think so.
