Beijing is definitely happening. The streets are crowded, there are endless buildings with very impressive architecture, and the only other city that seems comparable is NYC. Public transportation and bike access are great and I think some US cities could definitely learn a few things from the way things are run here. Preparations for the olympics are intense and I can't imagine how crazy its going to be here come this time next year, a fiasco at best.
Understanding the political/government system here in China has proved to be very intriguing and sometimes even disturbing. I've definitely learned a lot about this peculiar system.
All in all its been a really enjoyable and educational trip so far, though I can't wait to get to our final destination already!
