I was watching the opening theme credits on Real Player and was confused on which Northwestern Campus was used. There are two in the Chicago area: Downtown on Chicago Avenue and Lake Shore Drive an the other one is up in Evanston. My guess, is that they used the downtown Chicago campus. I saw pics of the Evanston campus, and I do not think Evanston's campus has thousands of trees. Plus, I could notice by the hundreds of people that were walking by, it had to be the one in downtown Chicago.
