Thanks Chrisg...I did get it finally but the definition doesn't make much sense to someone from the other side of the world, (it does now).
And in the past I wondered why I struggled with the many cryptics I attempted.
I don't like clues that rely on "local knowledge".
I believe a well written clue has the answer hidden (as this one did) but the definition shouldn't rely on "local knowledge".
Thanks once again.
