WUStock is on the Swamp this Saturday from 12-6 p.m., capping off Spring South 40 Week. The music starts at 1 p.m., with Sobriquet, String Theory and the Noam Chomsky playing in that order. Finally, Augustana will take the stage. The weather is expected to be great, so make sure to check out some of the activities, which will include a dunk tank, a face painter, a mechanical bull, a velcro wall and a giant slide.
