The American Red Cross in Nassau County (ARC/Nassau) encourages swimmers 12 years of age and older to join in its 15th Annual Swim-a-Cross on Aug. 20 at Centre Island Beach in Bayville. The Swim-A-Cross is a one-mile swim across Oyster Bay Harbor. All proceeds will benefit local ARC/Nassau services, including disaster relief and lifesaving programs in health and safety.

Check-in is at noon at Centre Island Beach. ARC/Nassau encourages spectators to come and cheer on the swimmers. There is no time limit to finish the swim, just swimming for a good cause. Participants must have a strong swimming background and must be able to swim a mile in a pool. A cooling station sponsored by the Kevin Scott Dalrymple Foundation will supply all participants and spectators with a shaded and cooled place to enjoy the summer day. Refreshments will also be available for all participants.

The pre-registration fee is $25 and day of registration is $35 at the beach. Raise $50 in sponsorships and receive a Swim-A-Cross T-shirt. Other prizes are available for sponsorships of more than $50. Sign up now and start to get sponsors. For registration information, call ARC/Nassau at 747-3500 ext. 215 or download a registration form from www.NassauRedCross.org.
