Somewhat related, Ravinia has a train stop right outside the venue and after a show - it is a complete nightmare to jump the train. Parking (travel by bus to the lots) is a rodeo as well. Point is - even if there is mass transit, as Tim pointed out - getting a large number of people to leave at the same time is gonna be a nightmare with or w/o mass transit. Right, people point out that Arlington Park has its own Metra stop and use it as a reason why a stadium in Arlington Heights would be easy to get to. It's one Metra stop on one Metra line. While there are cross-suburb highways like 355 and 294, by and large Chicago's infrastructure is built to get people to and from the city. Someone in like Tinley Park doesnt care about the Metra, they care about having to switch highways 3-4 times and then drive on surface streets not designed to send 60,000 people into a concentrated area. 53 is 3 lanes without any shoulders in the area near Arlington Park exit, and I don't think taking Rand or Northwest Highway is going to be any better.
