Calhoun College’s renovation appears to be on schedule so far, but when students move back in next fall, something may be missing: the courtyard’s signature tire swing. The college’s great elm and its attached swing were removed this spring to allow for the expansion of the basement. The college’s architects have yet to find a suitable replacement tree, and Calhoun Master Jonathan Holloway said in an interview that he is ambivalent about replacing it, even if they do find one. When the original tree was taken down, he explained, the courtyard was used more often because students had room to throw Frisbees, play stickball and sunbathe. Micah Hendler ’11 was among several Hounies to express concern to the News. “I remember swinging on the Calhoun tire swing when my dad took me to his 25th reunion,” he said. “I actually began my answer to the ‘Why Yale’ part of my college application with the tire swing.”
