A DAY OF STEEL, WHEELS, HEAVY MACHINES + FUN! Big machines return to Tellus for one of the Southeast’s favorite fall events! See helicopters land, hear the roar of engines and the sirens of fire trucks, and much more. And with few exceptions, kids of all ages can climb into or on these machines. There’s something for everyone at this fun extension of the Millar Science in Motion gallery – big machines, educational kid’s activities, photo ops, a sale in the Store, and a special cookout-style menu in our outdoor Café. Suitable for all ages.
