In the fifties and sixties annual formal and semi-formal dances were sponsored by the I.U. Center, each with a theme such as "Winter Wonderland," "South Sea Serenade," "Fantasy in Snowflakes." Informal dances included the "Bum's Bounce," and the "Leprechaun's Leap" (St. Patrick's Day dance). Dances continued into the seventies and beyond but were less of a special event than during this time period.
