Traditions Gustavus traditions include traying down the hill from Old Main in the winter, random Gustie Rousers, stargazing on top of the academic building Olin, playing tennis in the Bubble, and streaking through The Arboretum at Gustavus. Gustie traditions are mostly exclusively known by Gusties. Student organizations There are more than 120 special interest groups and organizations at Gustavus. Students are very engaged on campus. Active student organizations on campus have included Model United Nations, the National Forensics Debate team, and the Gustavian Society of Filmmakers. Students are encouraged to create their own clubs or teams and apply to Student Senate for funding. Nearly 1/5 of students are active in Greek life at Gustavus. There are ten recognized Greek organizations on campus (some have been suspended and are no longer recognized by the college). One prominent campus organization is the Campus Activities Board (CAB). CAB's mission statement is to "enrich the campus life experience by encouraging the involvement of all students in entertainment that is engaging and enjoyable." All students on campus are part of the Campus Activities Board and eligible to participate in activities, serve on committees, and apply for the Executive Board. There are 11 executive positions, not including the co-presidents and the advisor. Music Many musical ensembles perform throughout the year, including the Gustavus Choir, the Choir of Christ Chapel, the Lucia Singers, the Gustavus Adolphus Symphony Orchestra, Gustavus Wind Orchestra, Gustavus Jazz Ensemble, etc. In 1942, Percy Grainger, writing in The Musical Quarterly, publicized the "pathbreaking activities"—as an historically appropriate ensemble—of the college's A Capella Choir and chamber orchestra, which toured a series of concerts of music from the 13th to 20th centuries. He praised the "rare value", "practical skill" and "subtle esthetic intuition" of conductor G. Adolph Nelson. Grainger had an opportunity to observe the work of Nelson, the choir and orchestra at close quarters by touring and performing with them that year. Nelson was the college's musical director from 1930 to 1945 and the driving force behind a group that toured the eastern states, winning both critical acclaim and financial success. He was particularly concerned to revive and share the music of the chapel, including not just voices but also the instruments
