Look up Patriots Place. It's only a few years old.
There's a lot to do in the area and there is some really fun tailgating. You can buy into some of the radio station bus tailgates but also have tons of room to set up. Parking in the main lots are $40 per car while some of the other lots are $15-$30. Once you get off the highway there are irish pubs all the way down to patriots place that you can stop at.
I have friends coming up from nola and we'll be tailgate jumping at different Patriots parties.
