Was on the beach at Three Cliffs, Gower with my daughter Heledd, when we came across these curious numbered stones. Underneath each stone was a small piece of paper on which a single letter was written. We found four stones but know that at least 8 were hidden.
I'm blogging this as a bit of a "time machine" game. My hope that, perhaps in many years from now, the girl or boy who set up these stone clues will see this blog and be able to have a laugh that we chanced upon these mysterious clues. If you are that person, please get in touch no matter how many years go by!
