Merry Christmas Good fellow !! One tough man...no doubt! No Hollywood / MMA p/ social media phony...just the real deal. Much respect...as he leads by total devotion and example. There's a couple guys here too, that I'm just amazed by whom have had similar paths.... I wish I had them as friends. Good men!
