The first impression of Soul was that the country was nearly all bridges of some sort, as we drove from the airport that was just about all we saw. Overall South Korea is pretty much like China, except that the language is even harder to read than Mandarin, it looks like a Tetris game to me.
We had a trip up the Soul tower which has a great view of the city and surrounding area and shows just how big Soul really is.
We also had a trip to the DMZ (De-militarized Zone) on the border with North Korea, This is a very odd experience, it is kind of like watching schoolkids facing off to each other, the South's soldiers stand in an 'aggressive' mode all the time wearing sunglasses, they wear these to stop the two sides 'eye fighting' in other words glaring at each other. While there we had a trip down one of the Tunnels that the North had dug ready to invade, the joke in the south is, "Wasn't it nice of the North to build us a free Theme Park that we make money out of", there is also a theme park on the land next to the DMZ, I doubt that the North has such a thing.
Overall it was a pleasant visit, Soul is a girls shopping paradise and the folk are friendly enough. I'll post pictures when I get back home, as I am in the UK at the moment.
