Nearly 500 people have joined a Facebook group that encourages them to paint, hide and find rocks throughout the Vinton, area.

The woman who began the project hopes to remain anonymous, but says she is happy to see so many participate.

“I think it’s a great idea,” says Becca Ingham, whose children are among the most recent to paint rocks to add to the effort.

Participating is simple; just wander around Vinton, looking for uniquely painted rocks. After you find them, take a photo, if you wish, to share on Facebook and then hide them again.
