I miss biking. Spring and Fall in Seoul are perfect seasons to bike, the weather is fresh and the view is great. Summer is a bit hot and rainy, but winter is just nuts. I would not bike during most of winter, against icy wind that feels like many tiny knives cutting through your skin. Some people, though, have no choice. You gotta make a living and pedaling those two wheels is part of it. This man stops to clean his tortured nose as he transports trash for recycling, and I'd imagine his skin is probably thick and tough from having to tolerate such harsh conditions.
