Pa. town to celebrate New Year with giant mushroom (UPI) --A Pennsylvania town will celebrate the changing of years this New Year with a 700-pound stainless steel mushroom. The town, Kennett Square, accounts for about half the U.S. production of mushrooms and calls itself the mushroom capital of the world. Pennsylvania is known to have odd traditions for New Year's Eve, including the lowering an 85-pound Marshmallow Peep statue or dropping a 10-foot-tall illuminated crayon.
