I wasted time in the morning walking down the wrong path. I doubled back, probably adding two kilometers to my total walk. Later in the day, I found myself faced with another dilemma: Naver Map was telling me to take a path close to the river's bank, but when I saw the path, it had been ripped up and turned into a construction site.
The following set of photos leads us up to that dilemma. Everything had been hunky-dory until the road disappeared.
