I have been to Chicago once. To be precise I flew through it, as a hub, enjoying (if that's the word) the most frightening landing I've ever experienced on a plane.
We were a few minutes late and the (presumably ex fighter-) pilot up front was determined to make up time. He took us into such a steep angled turn that those on the right of the plane were looking directly downwards out of their windows. Passengers were screaming. Suddenly he snapped the plane horizontal. We landed, I kid you not, less than three seconds later. I was with a group of experienced airline staff, and every one of them was white as a sheet.
So you might imagine my second approach to Chicago was with even more trepidation. But no. In fact I didn't even notice I'd been. This is because that estimable newspaper, the Chicago Sun-Times has kindly syndicated my contribution to Vulpes Libris on its website. That's what I call virtual travel.
