I always liked stopping here when I was driving a tractor trailer. Never had trouble finding some fun. It's halfway between Boston and Providence, and 5min from 495, which makes it perfect for accessing.

As of now, it's all Male-on-male action, but I think it'd be a perfect place to have some ladies join the fun.

The Southbound side is an open lot with little to no cover. Some trails in the woods are semi private but pretty tight and busy. I think if you are looking to set up a co-ed event, you should look at the Northbound side instead. It's got large dark parking lots, and the information building is permanently closed. Right now, the guys tend to play in the shadows behind the building, but there's plenty of park benches and trees, and there are lots of trucks for cover in the back lot.

In all, this is one of my favorite spots. I highly recommend an after-dark visit to anyone in the area.
