The weather had been flawless for a good week after a miserable summer - unsmoggy blue skies, dotted with fluffy cumuli, hot sun cool shade. It was gorgeous; the sun spattered through the leaves as the wide trail wound its way up to higher heights, at a much steeper grade than our old daily walk in Gunpo. I got past the thundering-heart first ten minutes, and fell into the euphoric groove that exercise almost always brings, when I'm out in nature, senses heightened, brain clear.
