I'm not a huge baseball fan. I can follow a game, generally know which players are good, and can sort-of parse the statistics they flash when players come out. But my fiance's the one who really loves baseball, and so I find myself at PNC Park quite a lot.
It's definitely a beautiful and fun place to be. We love sitting along the third baseline for that amazing view of Downtown Pittsburgh. It's fun being along the river - I love seeing the excited people on the Gateway Clipper cruises.
More important, it's well-organized. Even though there are thousands of people at every game, there's always a restroom nearby and everyone's able to get out of the park relatively quickly. You have to love a space that can manage to be both beautiful and extremely well-organized.
