Didn't get to see much of it. Just went into the meeting area at the DMZ. Saw the fake city they built next to it. It's really bizarre. It looks like a legit city from far away, but if you use binoculars, you can see that all the buildings, skyscrapers included, are actually just concrete shells with painted-on windows. You can actually see the indigenous farmers that live in the DMZ driving through the 'city' with tractors.
Have to say, the DMZ is one of the scariest places on earth, just because you know you're constantly under surveillance, and there really isn't shit-all you could do about anything if the NK's did decide to do something. The US Army guys there seemed bored to tears since they were glorified tour guides, but the SKA treat that post like a religious obligation, and are permanently tense. Think an actually threatening version of the British Beefeaters. 50's-era helmets, mirrored sunglasses, etc. There's also a policy they have (which you can see in the photo) that the North Korean guard will never see more than half of a South Korean guard except the guy in the middle, who doesn't move. They stay in that position for hours. Their sidearm is on the 'hidden' side, should shit go down.
