I flew him into Tri Cities before the Bristol race one year. Probably '05 or '06. I didn't know he was back there until we got to TRI, and he was the last guy off the airplane. I wished him luck, and he promptly whacked his head on the overhead bins. Didn't seem to phase him much. He said thank you and went on his way.
Right after he was out of earshot, the FA looked at me and said "Do you know that guy? He's grumpiest SOB I've run across in a long time!". I nearly fell out of the airplane laughing. She had no idea who he was or that she just called him by name.
Four days later on the last day of the trip I had the pleasure of flying Bob Frey and Scott Kalitta back to CLT. Both were class acts.
Used to run across several racing personalities in the airports. I was talking to another pilot once when Mike Dunn walked up and asked how the other pilots' dad was. Spent a long walk to the baggage claim talking to Cory Mac in CLT. All those and the best was still the one with the least contact. The flight attendant calling him by name without knowing it.
