Armadillo Day began in 1972 when Northwestern University Texans held a small celebration in honor of the official mammal of their home state. More than 40 years later, Dillo Day continues as the largest student-run music festival in the nation, planned and produced by Mayfest Productions every year for the Northwestern community.
