This more an ongoing initiative that’s catching on social media for parents with children. The basic premise is to decorate a small rock (or rocks) with waterproof paint and then on the back leave the message “Photograph me and then rehide me” Also Facebook and your local Rock group. There’s one near to our base of operations in Tilehurst : Tilehurst Rocks. I’m getting the impression nobody minds too much if your child takes a strong liking to the rock they find. Remember to substitute for it though and also add others for other children to find.
If you have a local group doing this and want mentioning. Let me know and I’ll add you to this page! 🙂
