The Jamestown YMCA held its inaugural Zumba Monster Ball recently. The YMCA's four Zumba instructors joined forces to deliver a 90-minute workout culminating in a rendition of Michael Jackson's "Thriller." A gift certificated donated by Labyrinth Press Co. was awarded to Melissa Paterniti for best costume. Refreshments were provided by Pepsi Bottling Company and Farm Fresh Foods.
