The Kindness Rock Project

I guess it's a thing, even Google know about it.

Here is a picture of spot along my walk that has been deemed a Kindness Rock project spot, which seems to be monitored and refilled from time to time when running low.  

I've often seen these rocks hidden alone the way too, so they're not always found in one location.

In the end, if kindness fails you always have a pretty weapon at your disposal...
