Columbia Parks and Recreation is hosting a sensory friendly version of the Tons-of-Trucks event Wednesday from 4 to 6 p.m. at Cosmo Park. Touch-a-Truck is designed for young children and people with autism spectrum disorder. Event-goers climb in and check out their favorite vehicles without the lights, sirens and horns that can be upsetting. The event is free. More information is available at 573-874-7460.
