I did this last year for Montreal, and folks were kind enough to point out the errors in my proposed route. However, I actually live in St. Louis, and in fact live between the two Wash U campuses, and I take public transportation to/from the airport on a very regular basis. This year the information should be on target.

At the above link you'll find a somewhat detailed narrative with ascii maps and links to real maps. The info currently at that URL will get you to the registration building from the airport. In the future I plan to add info about how to get to fun stuff near campus.
Please post questions if you have them, as others probably have them too. Post your own suggestions of fun things to do (and maps, if relevant) as well."
