What a clean city this is.

Seoul is an amazingly clean city for its size. With more than 11 million inhabitants (that's larger than New York City!), you'd expect a certain amount of trash on the street, a lot of littering, cigarette butts, etc. It's absolutely amazing-you can walk on the sidewalk at almost any time, look up and down the street and have a hard time finding one piece of paper, one candy wrapper floating around. Not only is littering very rare, but when the leaves fall someone is there to sweep them up almost immediately. There is still an awful smell sometimes, that can take your breath away. You'll be walking along, and it will hit you in the face so strong that your eyes water. But even that you get used to (hey, for anyone who has spent more than an hour in New Orleans, this isn't too much to ask).
