With the exception of Yankee, Wrigley and Fenway, what are the oldest ballparks you've seen a game in?
I am sad to say I can only count Riverfront and 3 Rivers Stadium as the "oldest" ballparks I've been to (although have been to Fenway).
My father has been to games at Ebits field, The Polo Grounds and I'm sure several other contemporary ballparks.
