Eli Lewis, 11, switches his back wheel with his competitor before his first race in the 2013 Mid-Missouri All-American Soap Box Derby on Sunday on East Broadway. To ensure the times are based solely on the skill of the driver, each race takes place twice, with the racers getting a chance to drive on both sides of the street once, and they switch two of their wheels with their opponent before each run.
