So : no nuclear test blasts on Friday in North Korea (good), during the Day of the Sun military parade. The Rachel Maddow Show (daily news and opinion TV show) reported that the three-times-a-week flights from Beijing on Air China into Pyongyang has been suspended, though.
That still leaves the option of going there with Air Koryo, on a Soviet-era airplane (no jeans, no talking to locals, no traveling solo). As the Koryo Tours website notes : Travelling with us to Pyongyang, and beyond, is something you’ll remember forever.
