I suspect the radio prompt is from one of the people who worked in a lighthouse, part of the mundane routines there? I'll see what I can dig up.

I weighed treating Lost Keys and Looking for Keys as duplicates, but then recalled that I frequently spend large amounts of time looking for keys that are not lost, but rather have migrated to the bottom of my purse, under my wallet, my phone, and about a month's worth of crumpled receipts. I'd say to see how you can spin them differently! (And I curse the bingo generator for putting them so close together on the same card! Hundreds of prompts, and it goes and does that. Sigh!)
