I think I may have really "hit" on something very recently---OPERATIONS--on video which have been very well received. As many of you are aware, I did a "trailing vs. facing point" video to simply show how to accomplish these two most basic switching moves. I didn't expect a lot of views. I was wrong. Over 1200 and climbing in a very short while.
I followed that up with a couple of others which were received well. ALL may be seen by clicking on my YOUTUBE link below my signature.
Here is my newest. It is CLASSIFICATION 101 which is as basic and simple as any classification system can be. The best part? It doesn't require "extra" material, i.e., paper, and no computers, index cards, etc. This classification is ideal and fantastically simple yet offers active involvement/participation providing you and others with entertainment and fun!
