Pool party at the Double D today!

By Meredith Deliso

Suit up — the public pools are open.

On Wednesday, hot Brooklynites (and Mayor Bloomberg) took the first big cannonball of the summer as the city’s 54 outdoors pools opened for the season.

The opening couldn’t be more poignant than at the Douglass-Degraw pool at Thomas Greene Playground — affectionately known as the Double D. Last summer, the Boerum Hill pool nearly closed for good due to budget cuts. But, thanks in large part to efforts from the crawl stroke-loving community, who came out in droves to sign petitions and write letters to their representatives, the pool was saved two weeks later.

“The more people who come show how important it is for the area,” said pool advocate Sam Neely who launched a Facebook group to save the pool, at the time.

With that sentiment in mind, the Friends of Douglass Greene Park is throwing a party today across the street from the beloved pool to celebrate a wet, cool summer once again. There’ll be live music, games and food — just remember, wait 30 minutes after eating until swimming.

Party across the street from the Double D [Douglass Street between Third Avenue and Nevins Street in Boerum Hill, (718) 625-3268], July 2 from 2:30-5 pm. Free. For info, visit www.friendsofdouglassgreenepark.org.
