Somerfords Series #19. The cache is not at the published coordinates but it is on the series route ... somewhere. To find the cache you must have your head in the clouds, but don't worry: the cloud base is really rather low. Unless your head is already in tune with the clouds, you will probably want to ponder the cache location before setting out from home.
