The Metra and The Olympic Village Stop Question?

Ok, by our calculations it seems like the bid team intentionally left out the fact that there is a 27th street Metra stop right by the proposed Olympic Village. Why would they do this? We thought it provided them a great opportunity to connect the Olympic Village to the rest of the city with Mass Rail Transit.
From our calculations, there really are not many close CTA stops to the proposed Olympic Village (see chart below). The closest Red Line stop is the Chinatown stop which is approximately 1.5 Miles away. The closest Green Line stop is also about 1.5 miles away. So the CTA really won't be accessible to the Olympic Village.
So this leaves the Metra, which literally stops at the proposed Olympic Village. Let's also not forget that the Metra stops at McCormick Place and 18th street (both places that are either at or very close to proposed venues). So again why would they leave these off their maps? Are they hiding something? It's weird because they put random CTA stops on the map, but leave out major Metra stops that could actually affect the bid.

Not sure the reasoning, but the only logical explanation would be security concerns. Do the Athlete's only use buses? I imagine they do when they're going to venues to practice and compete, but when they're done wouldn't it be good if they could jump on a train and enjoy the real CHICAGO culture!

Just a thought on our part...can you think of any other reasons?
