This is a super cool activity!
It stands for West Coast Paint Rock.
My six years old loves collecting rocks and painting them. One day she found a rock painted and it had #WCPR on it.
It is a “rock” version of Geo Caching. If you find a rock, either you can keep it or re-hide it again. There is a closed group on Facebook which is used to see the progress on this rock hunt.
We have, so far, found three rocks.
Looking forward for some more rock hunting!
