Shanghai

Typically it takes a nearly $300 visa to enter China. However in Shanghai if you have a layover of less than 24 hours you are allowed to leave the airport.

With a 6 hour layover on my way to Frankfurt, I took the hour long train ride from the airport to downtown just to see this view. After taking a number of pictures using different exposures, I am still not sure which of these two photos turned out better, so both have been included.
