I know 2 of their "home games" were in Chicago north....but, remarkable that the Astros got outscored at home games in 2008....

Home/Road
Split           W   L      RS      RA     WP
Home           47  33     367     369    .588
Road           39  42     345     374    .481


and were 47-33 at home, including the 2 phantom home games in Milwaukee.
