River Action is hosting a bike ride scavenger hunt along the Quad Cities riverfront in June, called "Ride and Seek."
Riders are given a map with clues to solve. Those close are scattered around 36 different locations. Participants can then answer those questions online to win prizes.
The challenge spans from from Sunset Park in Rock Island, up to Cordova, and from Credit Island Park in Davenport, up to Riverdale.
People have the entire month of June to solve the clues. It costs $30 to sign up.
All the money raised will go toward riverfront improvements.
