Tomorrow is the start of the city's third annual Summer Streets program where the city closes down a 6.9 mile stretch of roads—along Park Avenue and other connecting streets from the Brooklyn Bridge to Central Park—to vehicular traffic. And this year, there's a new twist: Dumpster pools! Three pools, which have filtration systems, will be set up near the Grand Central viaduct—and yay, it's going to be beautiful tomorrow!

Summer Streets hours are 7:00 am to 1:00 pm tomorrow, August 14 and August 21. You can share your photos of the fun by sending them to photos@gothamist.com or tagging them "gothamist" on Flickr.
