11. take a walk everyday

Walking at a conference is no great trick. But "taking a walk" (for fun, health, and peace of mind) rather than merely walking for transportation can take some doing.

The convention center in Chicago doesn't make it obvious, but if you're diligent enough, you can make your way out to a marvelous bike/pedestrian path along Lake Michigan. I highly recommend that as a place to walk during a Chicago convention. I did it twice.

My last day at the conference had no free time. I intended to walk when I got home, but my flight was delayed so that it would be after dark before I got home. So, I walked the airport--all three concourses of Midway (Concourse C is short, Concourse A has the coolest stores).
