That can be a counter-counter-trick, that is typical for black ops, they make an urban legend telling you its something secret hidden in a sealed underground room right there in the park where you walk your dog every day, and you think yes right here in my park and not in a desert yes right for sure you want me to belive that you think I’m retarded right, but then it turns out to be true, they did it right there in your park because its so unbelivable nobody would belive it. Its what they call counter-counter-trick.
Its interesting if you get a chance to look it up but there was a military base there from WWI as it was a defence post against a Uboat Invasion of NY City. Yes the Germans did actually land several Covert groups through Long Island during both world wars.
It was a defence post till after WWII when it went from a coastal defence post to an air station till the air station closed in the 1980’s, It was a vacant lot untill the 90’s when the park was set up. Orginally they were going to demolish everything but it had become the last natural habitat on LI for several endangered animal species. It was then turned into a park. Conspiracy theorists still think it is an active facility due to some very restricted and patroled area’s by local law enforcement. They give the response that their are still dangerous hazards that were just left but the military when they vacated the area. Its an interesting read if you get a chance.
