On June the 14th of 2003, Macungie PA welcomed the long awaited ATCA Antique Truck Show (along with the warm weather). ATCA is an 'organization of persons who own, or have an interest in, antique commercial vehicles and who wish to promote the preservation, restoration, operation and history of antique commercial vehicles'. The truck show consisted of over 400 trucks, live music, food stands & over 200 flea market spaces.
