Shocktoberfest issues "Naked and Scared" haunted house challenge 23 (UPI) -- A Pennsylvania Halloween park is challenging visitors to pass through a haunted house in the nude for the "Naked and Scared" challenge. The Shocktoberfest attraction in Sinking Spring said guests can pay $20 after midnight, once the park's regular hours have ended, to pass through the haunted house for a challenge inspired by the Discovery Channel's "Naked and Afraid" reality show, WKYC-TV, Cleveland, reported Monday. The park said participants can go either "nude" or "prude," an option to leave one's underwear on during the challenge. Officials said only guests over the age of 18 will be allowed to participate and they will undress in a "semi-private preshow building" to keep them out of view of minors and non-participating customers. The park's website said the attraction is not meant to be sexual and "no sexual misconduct, inappropriate or disrespectful behavior will be tolerated."
