And for now about something irritating: See the orange truck in the background: http://www.youtube.com/watch?v=MGbQ7QRndcA&feature=g-vrec&context=G22d9758RVAAAAAAAAAA (maybe a maintenance truck for the overhead wiring?)
This truck, standing -obviously- at this crossing is visible other times, too, on pics of other tourists, but also in books! I stumbled over it last evening, when I read again in a book, a Swiss traveller has written in 2006 about his DPRK-trip.
