I'm not sure that is true — I mean the rich part is true, but not necessarily the rail enthusiast part. One of the times we took the California Zephyr there was a private car on the end that I understood to be some sports-team tycoon who was more or less afraid of flying.

There are definitely well-off people who are afraid of flying. My understanding is that Isaac Asimov was also one though I can't provide a reference.

Depending on how long ago it was, it could've been John Madden. Not a tycoon, but the first guy that pops into my head re: sports who refused to fly.
