Thanks to Korea’s particular love and appreciation of their own language, I did not have to work last October 9, or Hangul Day as it is commonly known here in Korea. Wanting to do something befitting of this wonderfully unique, Korean holiday, I decided that a walk around Seoul was in order. But not just any walk. I’ve done that plenty. This walk had to serve a purpose---it had to be both strenuous AND educational. And so with those parameters in mind, I decided to walk the entirety of the Seoul City Wall Trail.
