there is a huge mountain of granite here in GA called Stone Mountain.
On the surface of the mountain is holes and crevices that formed when
the granite cooled waaaaay back in the day. A letterbox can be shoved
into one of these holes and then plugged with a rock on top. I had
never heard the term plugging until I found a box on the mountain that
some Dartmoor folks had planted (the Squeeeezeboxers) and they
specifically referred to the box as "Box plugged under a flat topped
granite slab, amongst trees."
Anyway, just wanted to add that.
