Dig out your bathing suit and join in the fun of a polar bear plunge! The Special Olympics New Jersey returns to the Wildwoods to kick off 2015 with an icy plunge into the Atlantic Ocean during the annual Polar Bear Plunge on Saturday at 1 p.m. on the beach behind the Wildwoods Convention Center. The Polar Bear Plunge is a free event for spectators to watch, but Plungers must raise $100 in pledges to participate in the event. Early registration is available online by visiting www.njpolarplunge.org. Additional registration and donations will be accepted on-site the day of the event.
