If you’ve listened to the Union-Tribune’s “Science and Defense” podcast, or “Science Talk,” you know that co-hosts Gary Robbins and Scott Paulson are a couple of baby boomers who like old-time radio. (They especially love X Minus One.) During a recent podcast, Robbins and Paulson began spitballing ideas for a script they intend to write for a 10-minute sci-fi radio drama. The story, to be produced at wsRadio.com will be set in the 1930s and involves a man and his son (or daughter) who hear an odd noise emanating from an exhibit while they’re leaving a museum in Balboa Park at the end of the day. Robbins and Paulson urge readers to suggest names for the characters — and for a villain. They also want readers to suggest ideas for the plot!
