Though the rain washed most of their work away, it was the women of Chi Omega who painted today’s Rock. The sorority was advertising for their philanthropy event: “Make a Shirt, Make a Wish.” Participants can tye-dye T-shirts, tank tops, boxers and other articles of clothing, with all proceeds going to the Make a Wish Foundation. The event will take place Saturday, May 3 from 1 p.m. to 4 p.m. on the Chi Omega lawn.
