I met Walter Cronkite at Goose Bay, Labrador in 1982 or 83 in the USAF officers mess (of which I was an associate member), not long after he retired from TV. He was with a film crew doing a documentary on the Northern Lights and had come Goose for filming (Goose was a great place to see the lights) and crew R&R. He was gracious enough to sign an autograph for my father, who was a big fan. He enjoyed a few drinks and chatted away pleasantly to everyone present. I was, at the time, a young TV newscaster and was more than a little intimidated to be talking to such a lion of the profession but he was the perfect gentleman and treated me as a colleague.
One doersn't forget that kind of class, even if (or perhaps because) I am a Canadian.
