That's starting to change. I started going on long exploratory walks when the weather was clement. Then I noticed the big chunk of mountain right next to where I live and discovered hiking. Last weekend I bought a bike, and Seoul got a bit smaller. Tonight I'm going to cycle the few miles to Hyehwa and back. Granted we're going there for a curry, but still, I'm exercising! Plus I'll save a few thousand won in taxi fare.
Summer appears to be back, too - just as it happened in the autumn, the weather changed overnight. We went from freezing - it was insanely cold at the weekend - to 20 degrees this week. I went to work in just a shirt today. This is welcome news after the bleakest winter ever. Very welcome.
