A couple of quick facts about me, Emily Marie's son. I work in sports media and I have family in Wisconsin. Thus I decided to combine both facts and make a working vacation around the 2002 All-Star game. The game was quite a historical event itself, and I'd be happy to answer any questions elsewhere, but I was going to focus on the new Miller Park.
First off, I had been to the old County Stadium and I loved it. I never knew from all the games I saw on TV how much of that old-baseball feel it had to it. When it was closed, it still had only a dot-matrix screen, and the innards had catwalks like they have (had) in Tiger Stadium and Wrigley Field.
But that was then and this is now. Miller Park is pretty nice. My seats were in the lower deck in the outfield, but I felt close enough to everything. I never had a chance to check out the upper deck, but hope to eventually. Considering that the whole lower deck where I was seated was covered by the deck above us, I would guess the seats are pretty good. The highest seats looked like they might be fun. I can't really justify why, but they were right by the roof and yet looked like they offered great views.
Bernie Brewer packed up his house and moved to into the new park. So did the sausages (just ask Randall Simon). During the Home Run Derby, many of the league's mascots (even the sausages) took turns down Bernie's slide for each home run hit.
Like many of the new stadiums, you can walk around the whole promenade. That was nice. Also the walkways are redundant, so there's an inner and outer walkway. Many of the food concessions are opened on both walkways, helping to cut down on long lines. The walkway is wide open behind the center field wall. Out there, beyond the seats, is a retractable wall to help open up the stadium. Like the retractable roof, it can be opened an closed in a short time. During the Home Run Derby, they actually closed the roof but left the wall open. It was stranged to get rained on despite the closed roof. The park operators couldn't have been prouder of the roof. They made sure that everyone had a chance to see it in action. They even played "Also Sprach Zarathustra" to complete the moment.
Behind the left field wall there was a bar and sit-down restaurant where people can eat/drink while watching the game. It's very much like the restaurants in the SkyDome.
Getting to the park was a pain. Well, not if you have a car. Unlike most of the other new stadiums, Miller is suburban and not in or close to downtown. There is a bus line that is nearby, but that's about it. I did take a cab one time and it seemed reasonably-priced.
