Seoul - Now I Realize What it Reminds Me Of

A Nicer Pittsburgh
No, not because there are defunct steel mills or dilapidated buildings.  I mean the geography of the place.  It is hilly, every which way you look you see mountains.  There are rivers too.  We stayed right on the main river but there are many smaller ones as well.

If you were to knock down all the buildings in Pittsburgh and start all over and then add another 16 million people, it may end up looking like Seoul.
