Richard Kiel lived in my hometown of Oakhurst, CA. His son used to play basketball at the local high school with my older cousin. I went up to him at one of the games when I was 7 or so and shook hands with him. We'd often see him driving around town in his custom van. I didn't realize he was 74 this year.
He was very kind, very friendly to a small kid, and very, very intimidating.
