Sears Twr Skydeck
The Sears Tower just opened up a new skydeck, where you can stand on a piece of glass (only 1.5" thick!) and look down at the city. Now, I'm usually one to publicly avoid the touristy stuff - try to hide a map on the train, try not to gawk at the skyscrapers on my walk to work, etc... but I do love a good view, which might make it worth it to go check this one out. Maybe while "little e" is here this weekend?
