Kids Discovery Museum hosts Big Rig Day from 1 to 3 p.m. Sunday, Aug. 14.

Young ones can get their motors running and head over to KiDiMu for a truckload of fun. Spend a constructive afternoon getting up close and personal with some big machines from TILZ Compost & Soil in the museum’s parking lot, then have fun with a building project in KiDiMu’s Construction Zone.

The program is free with admission or membership.
