Which stadium that you have been to is the best to watch a game? I've only been to 3 outside of Texas. The old Yankee Stadium, Fenway, and Coors Field.
The old Yankee stadium was cool, but I didn't get nostalgia there like I did at Fenway. Fenway was an awesome baseball experience, and the crowd was pretty fun as well. I would have to go with Fenway as the coolest place I've been too.
Coors Field was great because I love Colorado, and watching a June baseball game when it's 60 degrees out is REALLY nice.
(When I went to the Yankee game, I got to get up the next day and drive to Cooperstown to go to the Baseball Hall of Fame. Not sure anyone has been there, but if you haven't you should go and take your kids. One of the best memories of my life.)
