MistaT unfortunately didn't get to see much of Boston since we got there the night before and left for New Haven the morning after the game, but the pre-game experience was far superior in Boston. With Gillette Stadium they've built surrounding bars, shops etc so that it's almost like a little stadium town, while MetLife was in the middle of nowhere. The Senegal game itself and the atmosphere was much better than Iraq though.
Got one day of sightseeing in New York the day before the game and I did like it a lot. A day wasn't nearly enough, of course.
