Anyone Lose a Giant Light Bulb?

Saturday I found this gigantic light bulb to the right of the boulders on Hole 3. It was slightly submerged in the leaves and dirt and I thought maybe it was some old and forgotten ordnance from the Fort Devens days. I brushed away the dirt and realised that it was a light bulb - totally not what I was expecting!

Amazingly it wasn't broken (except for the filament inside). Now to find the giant string of Christmas lights it went in!

No, that's not a mini that the bulb is on!
