I've always been fascinated by the Arecibo Observatory. There was a ham radio operator who was an early employee there. I met him at the Dayton Ham convention in the early seventies.

I planned a trip to Puerto Rico around ten years later. Unfortunately I suffered bad food poisoning on Guadeloupe and by the time I got to San Juan I was so ill that I had to cut out the trip to Arecibo. Still want to see it someday.
