I've been to County, Miller, Camden Yards, Wrigley, US Cell, and Riverfront and Shea, both in the years before their respective demises. I really liked Camden despite being in the absolute top row, it was sold out and it is in a really cool part of town near the water. Wrigley is what it is, meaning that you can appreciate the history even as you are uncomfortable for three hours watching a game. I'd have to say Miller Park is my favorite place that I've been to, just slightly over Camden, probably because I get to watch the Brewers there!
