In my time there, Trent University was a fertile field for message-based graffiti; mostly chalk, taking advantage of the all-concrete construction of Symons Campus. Some of it was more entertaining than others, particularly when it engendered a back-and-forth. This picture comes from November 2004, but I cannot remember exactly what it was dealing with anymore. At the time, food services at Trent were provided by the private company Aramark, but after seven years I can't remember what the deal was anymore.
Other graffiti was more along the lines of "sex kills but abstinence sucks," found in the library, and "Dopefish Lives."
