Course video

I have been using a discussion board on runnersworld.com to get more information about the Chicago marathon. Someone posted a video that takes you through the course. I have been trying to study the course a little just to know where key points are, such as half way, etc. The video is slightly different from the course this year, but it still gives pretty good perspective of how long the race is! It is nice to see there are a few areas of trees for shade. The finish line will be an amazing sight! I can't wait!
