So today one of my staff members reported hearing a weird noise coming from the ceiling in a large storage closet. It sounded like belts and pulleys squeaking. But there weren't supposed to be any of those above the ceiling! We had a couple of ventilation fan motors in the attic, so I went up there and checked to see whether perhaps those were somehow making a sound that filtered down all the way through the ceiling. No, they weren't.

So I climbed up on a ladder and pulled out a ceiling section about where the sound was coming from. When I shined a flashlight up in there I saw a strip of foil that had peeled away from a section of insulation rubbing against a piece of metal ductwork. The air blowing past it from the air conditioner had evidently worked it loose. The rubbing was causing a metal-scraping-metal noise that had sounded for all the world like squeaky machinery. I couldn't reach it, so I went and got a taller ladder. Now we've got the loose piece of foil out of the way and the noise is gone. Lucky I found out what it was before any of the Board of Trustees members heard the sound and wondered what was wrong.

I still say its a ghost.

Well, you're entitled to your opinion, but Velma and Fred both looked into it and they're convinced it wasn't.

Scooby and Shaggy, however...
