Screw all that noise about how cheerleading is only for jock arm accessories and the, um, unbrilliant, cuz cheerleading's back, baby. Check out York's cheerleading team (www.yucheer.ca) and all their rah-rah performances at games, demos and fundraisers, which they seem to take pretty freaking seriously. Or you can side with the nerds over the jocks and hit up Students for the Exploration and Development of Space (www.yorku.ca/seds), which deals with space travel and scientific advancements while keeping the floor open for debates on ethical issues like (possibly) "Should I dump all my garbage in space? It's endless, isn't it?!" and hosting guest speakers.
