Also had a great time yesterday. The shuttle service was outstanding. Coming from the brown lot, there was not wait, and it only took a few minutes to catch a shuttle back after the game. Traffic in and out of the stadium was also a breeze, in spite of my fears before the game.
Concessions also were a breeze, as lines were short and moved quickly. There's just food everywhere, and plenty of carts selling soda and beer.
As for the temp, it was way too warm. Everyone I saw in our section (448) was sweating, some profusely. It's not a function of the crowd or stadium design, as Chase Field is exposed to the summer sun all day before a game, and they still get that thing cooled off in time. Someone just needs to set the A/C down a couple of notches. Just a kink that will get ironed out, I'm sure.
All in all, a great day. Thanks CARDS!
EDIT: Also, while the video boards are great, the sound system was awful.
