Listened to the show for years ... back in the day. Never took any of it seriously but it was a good exercise in thinking about possibilities. Sci-fi and mystery, legend and lore.
Listened in on one of his round table QSO's back in the ESSB daze and thought it was something neat to happen upon.
I like to think he was a pretty happy guy. You could just hear it in the relaxed manner of his voice, consistent, for years.
