Ian,
The "Laird" bunker?
Hmmm. I wonder if that would have been a likeness of Robert Laird Borden, the late Prime Minister - and, I believe, a Nova Scotian...
As Tyler mentioned, the ability to use such humour without it taking over or appearing too gimicky is wonderful - something to be discovered.
That's wonderful.
I have yet to mention the question mark bunker at Digby to anyone who has noticed it ...
...and it's right there in front of you, clear as day - but just the right balance, so you have to be sensitive to discover it.
