In a fictional world where vehicles are living beings, a hotshot racecar named Lightning McQueen is off to a big competition when he gets stuck in a rundown desert town. His forced confinement has a silver lining, however: He eventually makes friends and learns that winning isn’t everything. Such is the plot of the 2006 Pixar Animation flick Cars. It and its sequel, Cars 2, will be shown outdoors on the lawn of the Green Music Center in Rohnert Park on August 12. Cars will be screened at 5 p.m. and Cars 2 at 6:45 p.m. Tickets are $5; ages 12 and younger get in free, though tickets are still required.
