Decorate a matchbox car and race to the finish line on a track made out of pipes and other materials. Participants will pair together to race the cars down the track. Regardless of which car zooms ahead, each racer can keep their decorated matchbox car as a souvenir. This Anythink in Motion bookmobile program will take place at Silver Creek Elementary, 15101 Filmore Street, in Thornton, Colo.
