Because it's so very, very far from the city... oh, wait, no, it's in the city, isn't it? It might technically be within Milwaukee's civic boundaries, but it's geophysically isolated from the rest of the city and accessible only by freeway (despite being built in an era when ballparks were being built to facilitate foot traffic) to where it may as well have been built in some remote Waukesha County suburb. Between this, the Brewers taking "Milwaukee" off their road jerseys the year they moved into Miller Park, and their sudden push to market themselves in Northern Wisconsin... even going so far as to claim the new park's roof was built to guarantee they could freely commute to games and not have to worry about rainouts... it's not hard to connect the dots to see who they were trying to facilitate. As for the whole needing to build Miller Park in the valley for tailgating thing.... I've never bought it. The old Park East Freeway was demolished around that time, and that would've been the perfect spot for a new Brewers stadium. God forbid I travel seven hours only to have a game rained out and not be able to attend the game(s). Target Field is in downtown Minneapolis and the atmosphere before the game sucks. Miller and its location are far more fan friendly.
