One a recent trip to China I had an opportunity to visit Nanjing. China's former capital is rich in history, Chinese culture and photo opportunities. It had been more than a decade since I'd been to China and I was struck by how much it has grown since my last visit. Evidenced by the bullet train we took from Shanghai to Nanjing, something that didn't exist 10 years ago. You can now travel between most major Chinese cities on high-speed rail. Our 180 mile (300 kilometer) trip took about 2 hours (including stops along the way), the train topped out at speeds of around 185 mph and most amazingly a round-trip ticket was $44, not much more than a tank of gas in the U.S.
