The DMZ border of North and South Korea is the most heavily armed in the world and a strange place to boot. Gmack asked the wrong question...something like "how often do joint security forces do military this and that @ this that and other areas?" and had his camera taken away and passport re-checked (he got them back later).
The top picture is taken at the border--note Russian tourists on top of building in North Korea and the soldier checking us out with his binoculars. Second picture is Gregorio bonding with Korean army dude, and the bottom is the bus station in Seoul.
