Zambesiboy: I am archiving this one as it seems it is problematic to keeping a cache here in good order. It was placed to add excitement to my event here and it achieved that together with a bit of fun for subsequent finders. I do not wish to have this cache become a disappointment for finders so better to release the spot to a new hider. If it is not taken up when I return I shall reinstall a new cache here.
Thanks to all those who helped with maintenance and to those that found it.
