I was going to go but I'll just watch on TV. Resale tickets are dirt cheap if you want to make the trip.
If you do go and want to park for free AND get a $50 Visa gift card, register to park in lots 45 or 55B. The catch is you can't leave for 75 minutes after the game. But the Patriots set up a free waiting room with snacks in their Cross Insurance center. It's a great deal if you can wait to leave.
