More volunteers are needed for the Iowa Games annual sports festival in Ames this weekend. Jan Williams of the Ames Convention and Visitor’s Bureau helps coordinate the volunteers.She says the games are a week earlier this year, and that’s surprised some people. Williams says you don’t have to be a sports nut or expert on sports to volunteer.She says the jobs are for timekeepers, scorekeepers, or even someone to check in athletes. She says they just need a few hours of your time.You can stay as little as two hours, or all day if you want. Williams says many people volunteer each year, and those core volunteers help train the new people. Williams says it’s easy to sign up by calling her office at 515-232-4032 or toll free at 800-2888-7470. Williams says they’ll work with you to find a time when you can volunteer. More than 13-thousand athletes are expected to participate in the games.
