The Fine Pair series was originally started by wizardsmum but is now managed by mattd2k.
If anybody would like to place 'A Fine Pair' of their own please do. I would just ask that you first visit www.afinepair.co.uk to request a number to avoid any duplication.
mattd2k also keeps a public Bookmark List of this series. Once your cache is published please contact him via at geocachingafinepair@gmail.com to have yours added.
