Dozens of communities in Suffolk are preparing for the annual going-away party for crime set for Aug. 7.

National Night Out encourages citizens to get outside, get to know their neighbors and present a united front against crime, all while having fun during block parties, ice cream socials, flashlight parades and other fun events. The goal of the event, sponsored by National Association of Town Watch, is to build crime-fighting partnerships with law enforcement and create a more alert citizenry.

During the night, one of several tour groups of city officials, law enforcement officers, firefighters and others visits each neighborhood. Judges rank the celebrations on a variety of factors, and awards are given including Best Community, Rookie of the Year and Best Business.

One of the lead-up events to the event is the National Night Out duck race, set to take place Friday at the TGIF concert at Constant’s Wharf Park, 100 E. Constance Road.

The concert will be performed by Slapwater, with the duck race taking place during the band’s first break. Citizens can stop by the National Night Out tent to meet the committee, get information on National Night Out and get their free ticket for the duck race.

In addition, those planning their neighborhoods’ events can enter to win a free block party from a national organization that has partnered with National Night Out.

Associa, a firm that provides management services for homeowners’ associations and similar organizations, will give a free Fall Safety Block Party, valued at $2,500, to a lucky winner. To enter, simply visit the company’s Facebook page, www.facebook.com/associa, and “like” it.

In addition, the company will donate $1 to National Night Out for each “like” through Aug. 7.
