Seniors gathered at the top of the Bell Tower Thursday as part of the annual “Bell Tower Climb.” More than 1,700 seniors attended, causing organizers to turn away “a lot” of seniors who lined up, said Senior Class President Dean Drescher, who added that many “took their time.” The event was a part of Senior Week, a full week of events just for seniors, including tonight’s Senior Ball, from 8 p.m. to midnight at the Carolina Inn.
