Here's an ok pic out my hotel window. River in the foreground is the Han River, which runs through the middle of Seoul. Beneath the tower is 'Itaewon', the "clubby" section of Seoul, and on the far side, kind of behind the bridge is the US military base. The Hyatt is the biggest light just beneath the tower and to the right, from where I took the picture below the last time I was in Seoul.
This is probably 1/50 of Seoul, but its a pretty interesting part. Fun facts of the day...about 25% of the population of Korea lives in Seoul, and when we get together for TV watching parties with our friends about 1/2 of 1/4 of the couples is Korean.
