Patrons were offered a "nude or prude" option for the "Naked and Scared Challenge" of visiting the house, undressed or dressed, the Pittsburgh Tribune-Review reported Friday.
Pat Konopelski, who runs "Shocktoberfest" on his Spring Township, Pa., farm, said, borough officials "took the position this is adult entertainment. This is not adult entertainment, but not wanting to pick fights with our neighbors or township officials, I conceded."
Mayor Francis Butkus said township lawyers were concerned that adding nudity to the macabre activities at the house, now in its 30th year, would violate zoning laws.
Scott Simmons, creative director of a nearby haunted-house competitor, ScreamHouse, called the decision to keep patrons dressed a stifling of creative freedom.
"Haunted houses are a form of artistic expression, and the most interesting expressions come when you burst through boundaries and don't listen to what people say should be," he said.
Konopelski said he will offer refunds to disappointed ticket buyers who intended to go through the house naked.
