Hiking Solo on Soyo

Hiking alone. You see this man? He hikes alone and no one seems to give it a second thought. Why? Well, first of all he's Korean, and second of all he's a man. It's natural (if perhaps perceived as somewhat sad by the group-loving Koreans) for a man to hike alone. He perhaps needs to think about big many issues. A woman hiking alone? A foreign woman hiking alone? Pretty unthinkable, I'd say. Anyhoo, I survived it. I hiked on Soyo alone before, but never on the weekend, always on work days (well, other people's workdays). The number of hikers was vey low, and I didn't feel especially singled out. Unlike today. So, why would a foreign female hike solo, other than wanting some time to herself to reflect and sort through things?
