in a series of caches where a red telephone box is in close proximity to a post box. The only rules are that they have to be able to be photographed together, be not more than 100’ apart and the phone boxes have to be red.
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 email@example.com to have yours added.
Please be aware that at the request of BT, it is not permitted to place the cache inside or on the exterior of the telephone box.
