Employees from the Mack Customer Center and Macungie Assembly Operations, both located in Pennsylvania’s Lehigh Valley, caravanned to Hagerstown, Md., for a memorial ceremony at the company’s powertrain plant. Following the ceremony, Lehigh Valley and Hagerstown employees traveled by truck and motorcycle to Washington, D.C., joining thousands of participants for the 26th-annual rally. The pictured Mack Pinnacle Axle Forward model was used as a tribute truck with commemorative decals.
