I think each ball park should remain unique. Could you imagine if they did away with the Green Monster? Even that little hill in Houston...definitely an oddity, but it's unique to that stadium. Different ball parks definitely add to the game. Typically, the really unique stadiums that you see now are hitter friendly. Personally, I think that old, pitcher friendly stadiums like RFK are boring...From a fans perspective, I'd rather see a game at a hitters park over a pitchers park anyday.
