George, he's posted a few times actually... I think in Vans forum under the alias "Pine Tree" which I think has something to do with Shorin Ryu. He hasn't trained in years but he encourages me to keep on it.
He actually lived and trained with his Sensei in the picture for many years.. he was very dedicated to Karate. I remember my mother taking me to his dojo when I was very young and watching them do kata... funny, the thing I remember most was my Pop heading towards me, lifting his chin up and breathing (some kabuki breathing exercise)! How ironic is that?
But to answer your question, no he's not training anymore..

I'm planning on visiting him this coming February. I haven't seen him in many years.
