I used to live in Wrigleyville and the explanation is simple. A couple years ago the City of Chicago designated Wrigley Field as a landmark. Landmarks in Chicago require the approval of the City Council for any changes or alterations to the structure. The Cubs aggressively opposed the declaration, but were powerless to stop it. The Tribune has made no secret of the fact that they would like to improve the ballpark by adding seats, expanding the bleachers etc. In order to get the approval to do so, they needed the City Council to give its ok. The City Council is made up of aldermen . Business owners and community members in the Cubs ward simply urged their alderman to pressure the Cubs into managing traffic, parking etc for the betterment of the community. The Cubs were forced to do so in order to get the approval needed for improvements. The City of Chicago is run by career politicians. Ask yourself this question, why were the White Sox given taxpayer $$ for a new ballpark, and more taxpayer $$ to tear some of it down, while the Cubs had to fight tooth and nail to get approval for an additional 2000 seats in an aging and decrepid ballpark, at their expense? Mayor Daley is close friends with the White Sox Chairman Jerry Reinsdorf. He's also a White Sox fan, who hates all that is Cubby. Politics sucks, but its how Chicago does business unfortunately. P.S. I work for the City.
