Each year, late in the spring semester, Senior Dining Out (SDO) marks the end of an era. The Seniors wear their uniforms for one of the last times and join in the celebration of four successful years in the Corps of Cadets. Ol’ Ags reminisce with each other and share stories of Ol’ Army days with the Cadets of today. The ceremony for the evening is a blend of Aggie traditions and military protocol. The evening culminates with the presentation of Cadet Awards and handing out SDO Challenge coins, and a video that captures the four years of Corps life of the Seniors. The event is attended by Senior Cadets and their dates as well as distinguished visitors and CCA Colonel level and above members.
