I'm sure you're getting a picture by now.
I don't know, Mark, you really didn't put in very much concrete detail about Dan.
Seriously, Tom, if you consider what already capable people like Mark and Marc are willing to do (travel a good distance) to train with Dan and his crew, that should be an indication that it is worthwhile. There is a full range of training opportunities available with Dan, from sophisticated solo and partner training ideas for internal strength/connection to honest-contact sparring.
As George said, you're in an enviable position given your location.
