shirty demon: I've had a good look for the cache container but it is either missing or buried in vegetation and well out of sight.
Also the location has changed appearance quite a bit since the time of placing the cache.
I think that it's time to say cheerio to this one and let it go with a rendition of Auld Lang Syne.
Many thanks to all of you who solved the puzzle and visited the cache.
I hope that you enjoyed the view across the valley.
