Down in "Research" I have been asked technical questions about the historical relationship of Daito-ryu and hapkido that are much more technical than I am qualified to answer. And, not really wanting to have two separate threads going, if y'all would drop down there and take a look, I'd appreciate it.
Or as Master Po says to Grasshopper (or should have, if he didn't), sometimes the answer isn't knowing the answer, but knowing who to ask.
