I am walking along the ancient city wall as it climbs a mountain ridge at the edge of down town Seoul. I am walking through a sort of residential park with a playground and some benches, to the right and behind me is the city sprawl with its busy streets and skyscrapers, to the left an area of small, dilapidated houses. If I stop to take a photo it gets cold quickly but since it’s up hill I warm up just as quickly.  Standing here writing this is making me cold, got to keep walking.
