ELLSWORTH AIR FORCE BASE, S.D.-- Courtney Abbott and DeRante Parker, an acting group from Chicago, Ill, perform their skit during a "Sex Signals" event here, Sept. 2. The presentation differs from traditional sexual assault prevention programs because it incorporates improvisational education, comedy, and audience interaction to provide a provocative look at dating, sex and the core issue of consent. More than 875 Ellsworth Airmen attended the event. (U.S. Air Force photo/Master Sgt. Loren J. Bonser)
