My buddy came in town this week and I got to be a tourist again, walking all of the Chicago landmarks and dealing with a million clueless people downtown.  Anyway, I got a chance to rediscover the Sears tower and their new glass boxes on the skydeck.  These are similar to the boxes at the Grand Canyon and are really fun.  Here’s a few pics from the trip up there.  And the Sears tower is officially changing its name to the Willis tower, but I have a feeling it will take a very long time for that to catch on.
