event, no one could be held responsible; under the proposed legislation, individuals participating could be arrested for illegally congregating on a state waterway. The Dartmouth Editorial Board quickly condemned the action and cited the rapid formation of "Save Tubestock" student committees. The Dartmouth reported on July 11, 2006 that a final town meeting had permanently put an end to Tubestock for those who did not wish to be arrested. Students organized an alternative event called "Fieldstock" to preserve "a class-unifying event and maybe even start it as a new tradition." First-Year Trips Established in 1935 to promote interest in the Dartmouth Outing Club, First-Year Trips is one of the largest pre-orientation programs in the country, involving over 90 percent of students in each incoming class. "Trips" has evolved significantly since its creation, becoming steadily more popular and intricate. During the 1960s, under the support of Dartmouth President John Sloan Dickey, the College renovated the Moosilauke Ravine Lodge, made the Lodge the final destination for all Trips, and brought participation up to two-thirds of the incoming class. Today, Trips takes place in the two weeks prior to the standard orientation week, and involves a three-night, four-day trip of hiking, kayaking, canoeing, biking, rock climbing, organic farming, nature photography, among other activities, culminating in a tradition-filled night spent at the College-owned Moosilauke Ravine Lodge. Run entirely by current students, these trips feature crews on campus and at the Lodge who welcome the incoming students and teach many of the traditional College dances, songs, and legends. Between six and ten incoming students are led by two current students on their trip. Trips is designed to welcome the incoming students to the College and to introduce them to various campus traditions. Up to one-third of the eligible current students apply to be a trip leader or a support crew. The First-Year Trips program incorporates many traditions, including a screening of the 1937 ski film Schlitz on Mt. Washington and the singing of the "Alma Mater" and the dancing of the Salty Dog Rag to a song of the same name by Red Foley (mp3). (The Salty Dog Rag, which is a traditional American dance, was brought to Dartmouth by Mary Heller '76, who learned it when she attended The Putney School.
