In Seoul airport. Saw a baseball game on TV, downloaded a bunch of apps on Fast wifi, and thought "It's great to be back in civilization!"
Let's just say this: as sad as we were to say goodbye to our friends at the airport Burger King, we were just as happy to leave Shanghai on a d ay when air pollution was over 200 all day. That's hazardous for kids and old folks, BTW.
About to board plane to Hawaii. Can't wait!
