In 1989, I moved to Houston to go to school. I had been training in TKD for years and was hooked on KMA's and saw a big bill board on FM 1960 near the Willow Brook Mall that read "Chung Moo Do", 8 martial arts taught as one".
So, I went to check it out. All I can really say is that I got a wierd vibe early on. The instructor slept in the dojang, the lights were always out (we trained by the ambient sunlight that spilled in from outside), and they were indeed particular about where you went in the building.
After about 4 lessons, I elected not to go back. I started receiving calls from an instructor that I'd never met. He was making claims about how study in their system would ensure that I made better grades and all the spoils of an "astute" student. He also praised my hard work in the dojang despite the fact that I'd never seen him.
The calls stopped after a few weeks but, it was unsettling how they were. It just appeared "hinkey" in my opinion.
That's my story and I'm stickin' to it.
