Associated with The Fence is a set of traditions at Carnegie Mellon University.

"The Senior Fence on the Cut was erected in 1923 so seniors could sit and watch the world go by. Three administrations were unable to remove it. It continues to be a jealously guarded billboard for campus activities and "unsanctioned announcements and editorial comments on campus life." The Fence receives more coats of paint each year than any building or canvas on campus. Students camp out at the Fence during the night to "stake their claim." Tradition dictates they do their painting only at night. Daybreak reveals new messages, from happy birthday greetings to an ad for the next big party." ~ From the CMU website www.cmu.edu

I've heard that the fence takes the prize in the Guinness Book of World Records as the world's most painted object.
