KaBoom, a charity that builds playgrounds, got a plug today from the country’s most prominent anti-obesity advocate — First Lady Michelle Obama.

Speaking to the National Parent Teacher Association, the first lady called KaBoom a “terrific nonprofit organization” and urged people to go to its Web site. “Right now they’re working to map every single playground in the county so that parents can find the closest one in their neighborhood,” she said. “I encourage you all to check it out and add the playgrounds in your own community to their list.”

Ms. Obama’s speech highlighted her new “Let’s Move” campaign to end childhood obesity within a generation.

KaBoom issued a statement acknowledging the first lady’s remark and said that once it has “a comprehensive map of the state of play across the nation, we’ll be better able to target underserved areas, influence public policy, and help parents ensure that their children will have a great place to play every day.”
