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 at Ellsworth Air Force Base, S.D., 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)
