^Back then it was more about "going downtown for a big game" as the end-all be-all of your day, rather than "I'm entitled to drive where I want and then drive back to the suburbs when I want, if there's some sort of football game en route, that's an added bonus."
Unfortunately that mindset has totally prevailed, and now all modern football stadiums are designed to get people, mostly drivers, in and out again as fast as possible. It's sad, it used to be a great draw to get people to come downtown.
