Subway: super convenient, efficient, easy (English on signs), cheap (less than a $1 per ride), clean and goes everywhere! Impressive!
Food: tasty and cheap (both street vendors and small restos)
People: lots of them. Mostly looking at their smart phones. But friendly.
Weather: cool. High of 12 C / 54 F. And going to get colder.
DMZ Tour: very interesting (and I got to step into North Korea, inside a little building).
See map in progress
More on everything tomorrow.
