The DeMilitarized Zone (DMZ) is one weird place.
It's weird that it is apparently the only DMZ in the world, but the barbed wire, tanks, soldiers and landmines suggest that it is actually really militarized.
It's weird that what was one country is split into two by a river, a Southern Line Limit (SLL) and a DMZ, closer than the north and south sides of Sydney Harbour. Imagine if people were shot or jailed for trying to get to Circular Quay from Kirribilli.
It's weird that families were separated indefinitely and had no means of contacting each other, yet the north built underground infiltration tunnels with the intention of invading the south, like when you crossed the line dividing your half of the bedroom from your siblings half.
It's weird that this area which is so contested and has numerous war memorials, also has an amusement park and has been turned into a major tourist attraction with the aim of unifying both sides.
