Fulton Rocks is quickly gaining followers in Callaway County.
"Our group has grown to more than 2,000 members," said Jessie Staats, who started the group. "It's amazing to see how fast this has grown."
The group aims to share positive messages by painting small rocks which are then placed in random locations throughout Fulton. When those rocks are found, the finder has the chance to put the rock elsewhere for someone else to find.
Staats said people are getting out and hunting for the rocks, and the once-small group has spawned a bigger statewide movement.
"The local children are enjoying it and getting active and having a good time," she added. "Since we've started the Fulton group, there's also been a statewide group started. If people are not from Fulton, they can find a group where they're at or start their own."
The group started placing rocks around town about the same time Pokémon Go, a mobile game where the player searches for Pokémon in real-world locations, became popular. Staats said the Fulton Rocks movement may have been boosted by people playing Pokémon Go.
"I think it could possibly be related. People are out collecting Pokémon and find the rocks," she said. "I think in some way it's increased the popularity. We even have a group member who is painting Pokémon characters and pokéballs on rocks for people to find and catch."
Fulton Rocks is exploring hosting an event at one of the parks in Fulton where rock hounds can get together and share their love for painting, placing, finding and replacing the rocks.
"We are currently planning on putting an event together for everyone enjoying it," Staats said. "We're trying to get donations and sponsors together."
