It's during the end of Spring Semester and if you can't hear the party you sure can smell it. Pigma is an annual pig roast hosted by Omicron Sigma Omicron. T-shirts are sold at the college center and Westerlin from 5-7 pm a week prior to the event. Omicron Sigma Omicron would like to thank all those for coming out this year, it was a huge success.
