(HANNIBAL)--Over 300 kids have properly fitted helmets and clean bikes…safe bikes following Saturdays’ Ride Cool event sponsored by the Hannibal Clinic. Ride Cool events also included a bike inspection. Nationwide… more than 500,000 people go to the hospital every year as a result of a bicycle related injury. Event Organizer Ginny Webb with the Hannibal Clinic says it's important to keep track of your kids' growth to make sure their helmets continue to fit properly.
