I should take this time to tell you a little bit about the Seoul Metropolitan Subway. If you're like me, and the only experience you've had with city train transit is in cities like Edmonton, the Seoul Subway is quite a shock. In a city as densely populated as Seoul, an efficient rail system is key, and it is really amazing how well the subway here works. There are nine different lines in the system, with a total of 291 separate subway stations. You can quite literally get to almost any part of Seoul using the subway system. On top of that, the trains and stations are, without exception, nearly immaculately clean. The trains are very modern and obviously well-maintained. To give you an idea of the scope of the entire system, here is the map of the Seoul Metropolitan Subway:
To me, it looks as though someone has dropped a bowl of cooked spaghetti on the city. Crazy!
