It's very possible that this is a photo of Naval Air Station - Rockaway, in Queens, NY. It is identifiable by the building at the top of the photo, in the background, which appears to be US Lifesaving Station Rockaway, which was located just west of the air station, in Fort Tilden. Best guess on the date is sometime in 1917, soon after the air station was established.

This and the photo below, among this latest group of LOC Bain photos to be posted, is a photo of a US Navy C-Class blimp. See: en.wikipedia.org/wiki/C-class_blimp For comparison purposes, see also this newsreel footage of C-Class blimps posted on YouTube by CriticalPast: YouTube - Critical Past: "U.S. Navy C-class airships at Fort Tilden, New York HD Stock Footage"

Looks like Rockaway is correct, see comment under

Art Siegel Excellent! Here's additional footage of a C-Class blimp taking off from the airship hangar at Fort Tilden (adjacent to NAS Rockaway) for a flight over Manhattan. The building in the photo on the left side of the frame is captured at approximately the 48-second mark of this film.

According to books.google.com/books?id=Sf-ZDQAAQBAJ&pg=PA39-IA8&am... the Police Field Day Games in 1920 were on August 29, at Gravesend Race Track.

en.wikipedia.org/wiki/C-5_(blimp) "C-5 was a hydrogen inflated C class blimp operated by the U.S. Navy in 1918 and 1919. It was one of ten C class non-rigid airships built by Goodyear and Goodrich primarily for training and patrol duty for the navy during World War I. The C-5's engines were built by Hispano-Suiza, and its control car was built by Curtiss Aeroplane and Motor Company. In early May 1919, the C-5 made a pioneering flight from its home base at Cape May, New Jersey to Montauk Point, New York and St. John's, Newfoundland, becoming the first airship to reach that city and in the process sending the first radio voice transmission from Newfoundland. " However, the transatlantic attempt, of which that was supposed to be the first hop, was a failure. When at St. Johns, Newfoundland, a "cord broke, and the C-5 began to lift off, tearing a few remaining cables that injured two crewmen as they sprang loose. Little jumped from the rising blimp, injuring his ankle, and the C-5 was blown eastward, over the Atlantic Ocean."
