Zac Does Chicago

Zac has been spending some time in Chicago recently as he has met with some clients through his business.  He never has much time to play, but on this particular trip, he did take a ride to the top of the Willis Tower (Sears Tower), which is now the ninth tallest building in the world (though it was at one time the tallest in the world?  I think.)  The views were pretty stunning and they even had a glass walkout that you could walk out on and get an almost 360 view of the city.
