For those keen on Korean War history I highly recommend a visit to Demilitarized Zone dividing the South and the North. My intention was stand at each side of the border and feel the impact of armistice. First it was the South Korean side and only one week later I was standing at the viewing point in North Korea. I can only add that South Korean side of the border was less relaxed and more controlling and restricted to visitors, also heavily guarded by UN troops.
