Lew Keppler was affiliated with one of central Pennsylvania’s best-known senior corps: the Milton Keystoners. He first played bugle with the junior corps in Milton, then marched as the Keystoners drum major for nine years, winning six best drum major awards. He was also the drill instructor and business manager for many years. Under his direction and management, the Keystoners won two Senior B class American Legion (AL) state championships and one Senior B class Veterans of Foreign Wars (VFW) national title. The Keystoners often had higher marching and maneuvering scores than such nationally-recognized corps as Reilly Raiders and Archer-Epler Musketeers. He served on the Pennsylvania Veterans of Foreign Wars (VFW) contests committee. In the 1950s, he was well-known as the organizer of the popular Cavalcade of Champions annual contest, held in Bucknell University stadium.
