Anyone heard of these? They've been appearing on my Facebook timeline for the last few weeks. People paint designs on stones, stick a label on the back with the name of the Facebook page and their smile stone nickname and then hide them somewhere. If you find one then you photograph it, upload the pic to the Facebook page along with the painter's nickname and then rehide the stone and hopefully it's journey around the country, or even the world, can be followed.
I found one this morning whilst out with Billy! The name is correct, you really do smile when you find one! I've got to think of somewhere to hide it now. We've got a few days out planned so I might hold onto to it and hide it further afield in a couple of weeks.
