We used to do it a lot, not so much now. At one time we owned 4 caches and enjoyed seeing the pleasure people got from finding them. Just before we got married we founf a bug, a small plastic crocodile called Cody who wanted to travel. We took photographs of it on a beach in Fiji, then looking at Syney Opera House before dropping it at a bug hotel in the Botanical Gardens. I hope the children who owned it were pleased.
Now I have a new phone with gps on board I might have to download the app and give it a go again.
