Do you know Roger Harpel? - December 11, 2004
Tom Harpel asks: 16 years ago, my father left Washington state for Thailand. For the first year, he sent letters back home but eventually stopped communicating.
I wonder if in your travels you have met him? His name is Roger Harpel. He lived in Washington state and ran a software company called Cosmos until 1989. It may be a long shot but the world can be surprisingly small. I look forward to your reply.
