Here are a couple of Joint Security Area (JSA) links for you.  First of all here is a Stars and Stripes report on the monthly training of the US security battalion located at the JSA.  The second link are pictures from John McCrarey of his trip to the JSA.  He has some pretty good pics of the place for those who have never seen the place before.  By the way if you live in Korea and haven’t done a JSA tour yet, what are you waiting for?
