As it stands right now.
I like the traffic getting into and out of. Especially the direct route to and off the 5 fwy carpool lane. Most of the parking is good, although the under the fwy exit does get congested at times. I've never had a problem on the State Street exit. And never used the Orangewood exit.
Also, exiting the stadium itself before you get to the car is smooth. With the old style ramps going down, it's very easy to get from seats to car, without too many issues even from the top level. By far, the easiest of the stadiums I've been to.
Field is visually ok to look at. Ever since they took down the mausoleum and converted to pure baseball, the outfield isn't bad. That one clear day you can even see the mountains.
Seats and the Suites are a bit antiquated. everything runs parallel to the foul lines. So the further you get away from the infield, the more you have to strain to watch the game. As you can see from the pizza throw in even Boston, those outfield seats are facing the infield, for a better view of who you want to throw your pizza at. I really do not think that this is a simple fix, since it's structural in nature.
Bathrooms. Never had a problem. But I hear the plumbing might be the issue.
Food and Drinks. There are plenty of vendors. It's just that they suck. I think some have said the inner workings of the concession areas are bad. Just not sure how much I believe that, because no matter how bad the workings are, you should not get a flat and soggy hot dog.
Advertisements. Just blinding. And it's everywhere. One of the bigger reasons I don't like watching the game live at the stadium. It's just horrible. I usually end up with a migrane if I go to a game.
Train. I do like that the train is right there.
