When you look over the DMZ you can see two flags that of the north and that of the south which designate the settlements of the two sides. People live in the DMZ which I think consists of military personel, support staff and some farmers who get paid quite well as they do occassionally get taken hostage.... although apparently not too recently! Its a unique scene seeing the divide between the countries and because of all the mines it hasn't been developed at all and is really green - I think its recently been designated as a national park because of all the wildlife and plants that grow there!
