Well, I've gotta warn you, there is security..
but many people have gotten in.. you just have to know how/where/when..
you'll most likely find other people trying to do the same thing if you go on a friday/saturday night.. and you could talk to them about how they've gotten in.
It's right by Kings Park High Schoool.. or is it Middle Schooool.. perhaps.. but Old Dock Road.. in Kings Park.. once you find that.. you're pretty much set..
And do keep me updated about it..!
