Aggie Muster Aggie Muster is a tradition at Texas A&M University which celebrates the camaraderie of the university while remembering the lives of alumni who have died, specifically those in the past year. Muster officially began on April 21, 1903, as a day for remembrance of fellow Aggies. Our family is going tomorrow to a local Aggie Club. There is a candle lit and roll call will be said. We shall say "here" in honor of the Aggie not present. This will be truly a honorable experience.
