A Pittsburgh bowling alley’s “Balls Out Bowling’ event is turning heads. The Pittsburgh Area Naturalists group has rented out Crafton Ingram Lanes for its bowling-in-the-buff event April 28. There are some rules for the event. No photography, video, or phones are allowed. Plus, the group says "Nudity is required (with the exception that women can wear bottoms). Please bring a towel and a bag for your belongings." The event page also states that there’s no hooking up at the bowling alley and no harassment. Tickets cost $25.
