Inside North Korea facing South Korea (world's most dangerous border)

We traveled from Pyongyang to the Demilitarized Zone, passing villages and checkpoints before visiting the signing room and viewing the heavily guarded Blue Buildings, although we could not cross into South Korea. We then had lunch, visited a museum and viewpoint, and stopped at the monument representing Korean reunification. After dinner and a live show, we explored the Yanggakdo Hotel and ended the day preparing for our long train journey out of North Korea.
