They’ll be trying to keep their minds and balls out of the gutter. A Pittsburgh bowling alley is letting it all hang out with a special bowling event next month that organizers promise will be “an unforgettable night.” Hosted by Pittsburgh Area Naturists, a nude event called “Balls Out Bowling” will be held at Crafton Ingram Lanes. But there are ground rules including no hanky panky. “Nudity is required (with the exception that women can wear bottoms),” the group said on Facebook. “Sexual activity is not permitted. Nudism does not equal consent and harassment will not be taken lightly. Violators will be asked to leave. No photography or video allowed.” Participants are asked to bring a towel and the event is open to bowlers of “all skill levels,” but only if you’re over 18. The organizers do more than just hit the bowling lanes, and host a wide range of nude gatherings including naked karaoke and naked trivia nights, according to their Instagram page.
