Navigull: I have decided to archive this cache as it is no longer in place.
Quite a story actually.
I received a email from craigkarenmathew who had found the cache container at low tide well out from Point Chev beach cast up on a sandbank.
He diligently set out to research its origin and registered on the geocaching .com website to track me down and advise me of its fate. We might even have a convert. Thanks Craig
I suspect it has been "discovered" buy uncaring muggles and any replacement would likely suffer a similar fate
