20 years or so ago I nearly bumped into him while scurrying between flights at O’Hare airport. He was just sort of gazing into space, like he wasn’t all there.
In 88 on the plane to my first duty station in Tustin, CA, I had the chance to meet the guy before the layover in Las Vegas - very humble in those years of his life as the Parkinson’s had already taken ahold of him ... He did clown a boxing pose at me and smiled - never forget that :-)
