I came back to St. Louis last night after staying in Shanghai for the last 10 weeks. The united 836 flight from Shanghai to Chicago took about 13 hours; it took another 5 hours to get from ORD to STL (4 hours stop over included). At one point during my 4-hour wait, I thought about driving from Chicago to St. Louis only takes 5 hours (300 miles). When I was in China, I heard about the MagLev (bullet train) from Shanghai to Hangzhou. It will take half an hour if completed (100 miles), making Hangzhou more like a suburban of Shanghai.
