It's every other Friday, just as the sun begins to make its way toward the horizon off Jennings Beach and most beach goers are packing up their belongings to head home, that the party really starts.

The DJ cranks the tunes, children dance, jump, shake and groove for a few hours while their parents enjoy each other's company. After exerting all this energy, families can lay back on a blanket on the beach and watch a movie on a big screen under the stars.

It's all part of the Sand Jam Family Fun Dances, organized by the town's Department of Parks and Recreation and promoted by the Fairfield Fitness Council. The dance portion takes place from 6:30 to 8:30 p.m. and the movie follows.

The next Sand Jam will take place Friday, July 16; it's sponsored by the Bank of Fairfield.

Additional dates for Sand Jam Family Fun Dances at Jennings Beach are as follows:

- Friday, July 30, sponsored by BMW of Bridgeport and Sportsplex@Fairfield.

- Thursday, Aug. 12, sponsored by the Bank of Fairfield.

For weather cancellations, call 203-256-3144. The movie schedule will be announced on the Fairfield Parks and Recreation website, www.fairfieldrecreation.com
