Jes, Terry , Bruce, thanks for the great comments and info.
Jes & Terry : The Pinetree line website still exists and it is alive and well . It is now hosted by the Jimmy Museum in Kingston. I will try to find the link for you but I have been on it several times over the last year or so..
Bruce : Brilliant . That's the guy. Now , why would the Chief of Naval Staff drop in on such a little , remote and relatively unknown Naval installation do you think ? Remember that at the time the site could only be reached by boat as there was no causeway . Suggestions ?
The MLU site is fantastic for this kind of stuff.
