It's a bit--evasive, let's say--to claim that, "if you want to see the system, go train there with gear on." Just for openers, the system I'm talking about wouldn't be visible in a couple of lessons and a couple of techniques and a bit o'sparring. And I have no desire to learn tae kwon do. I can explain enough about the basic system of kenpo, right here, right now, that people who didn't know anything about kenpo would understand--whether or not they thought that kenpo was worth a damn. You, too, should be able to explain; if you can't, something is off.
