Ah, the DMZ.
I used to work in a section that would go to the frontline ROK divisions to do Mobile Training Team work. I was at the ROK 5th Infantry Division, and we were doing a "tour" of the DMZ area. It was summertime, and there was a forest fire burning in the 'Z. They just let 'em burn, because it's not worth the effort to put them out. At any rate, I'd hear an occasional explosion, like a range was nearby. I asked the Captain I was with if it wasn't just a little dangerous to have a live fire range so close to the DMZ. He replied that "there's no range; that's the forest fire setting off landmines inside the DMZ".
