I just got back from North Korea and am now living in South Korea--AMA!
I went on a four day trip to the DPRK through a tour company and spent most of my time in Pyongyang. I visited during Liberation Day and saw some amazing and surreal things, including the DMZ, the Palace of the Sun (Kim Il Sung and Kim Jong Il's mausoleum), the Korean War Museum, and even got to drink some beers with locals. I'm now in South Korea for a couple months and most people are totally shocked when I say I just got back from the North. The big news here (as you can see in my proof below), is that Kim Jung Un is missing and there are plenty of rumors about what happened to him.
UPDATE: Someone asked about the propaganda so I uploaded some images here. I also included my favorite anti-American postcard, which was available in the gift stores.
