Eisenhower Park would be a nice spot I was at a bbq meet there yesterday
EDIT: Not the best video, did through my phone but a lot of parking space; oh this meet was kinda cool and dont mind me talking and my bad carmera skills lol
all i can think of is sunken meadow because of that huge meet. we can go there since it's a huge area...but 10 bucks to get in..if you're in the ny area it's basically easy to get to and little to no tolls for some of you.
