As part of WNYC’s Affordability Project, we’re collecting strategies for free summer entertainment. And when it's hot, the over 50 free public pools in New York City become a real life-saver for many residents, especially kids whose parents aren’t spending (or can't afford to spend) big bucks for summer camp.

What are some of your other free summer activities? Tweet @WNYC with #affordnyc or comment below.

And good news: The pool season has been extended to September 10th!
