Time Out says
Would you believe us if we told you a dip in the Atlantic is great for a hangover? Even if you don’t buy it, cheering those brave—or crazy—enough to take the plunge will stir you from your stupor. The Coney Island Polar Bear Club’s annual New Year's Day Swim invites hundreds of swimmers (without the benefit of blubber, underfur or guard hairs) to venture out into the ocean. All that’s required to take part in this brisk tradition are warm clothes, sneakers you don’t mind ruining (or surf boots, if you’ve got them) and the fortitude to actually go through with it. Meet on the Boardwalk at Stillwell Ave, Coney Island, Brooklyn. Suggested donation $25.
