This will come as a shock to no one, but I love SFO. When you're on approach to land, you come in over the bay and you don't see the runway until you're barely above the ground. It's completely unnerving if you don't already know that's going to happen. But what I like most is when you walk outside for the first time and get big blast cool marine air. It's breezy, it's salty, it's refreshing, and it's something you don't get to experience in the midwest. The airport itself is fine. With all the freeway ramps, BART tracks, AirTrain, and other transportation infrastructure leading to the terminal areas, the outside looks like a bowl of concrete spaghetti. Once you know it, you can navigate just fine.
