I don't really understand the negative commentary on blue line considering that the amount of time it takes to travel from O'hare to the Loop is mostly a matter of distance. The Jefferson Park and O'hare extensions are relatively new pieces of track, especially when compared to the Red Line. The only big problem I see with the blue line itself is that you can't express any trains since there are only two tracks. The Rosemont location has enough proximity to the city (and the suburbs) to be more viable than a lot of the other suburban ideas. The transit options would evolve over time, possibly with some East-West Bus Rapid Transit which would connect some of the train lines and the north side. Also keep in mind that Metra, CTA and Pace will be moving towards a unified fare system by 2015, so it would be easier from a fan perspective to use some of the integrated services. All this being said, I hope the strengths that I see in this option are only used as a bargaining chip to get a better deal for a Wrigley renovation and associated revenue. Sentimentality aside, it seems that a lot of the Cubs value as a brand comes from the history and imagery which is tied into the location and the park. The fact that this can happen without any public money is a pretty big accomplishment.
