Some move on from Korea and live there; others just visit. Many blog about it, and The Joshing Gnome even spoofed that tendency.
But blog pals Schwim and Foreign/er Joy both went to Japan for Winter holidays recently, and Schwim took some really lovely pictures, while Joy kept a nice, detailed day-by-day account, and loaded it up with explanations, but also put up tons of pictures, for those of us with short attention spans. Go read them.
Update: OK Korea did one too.
Thanks you two. I'll start reporting on my China trip soon: I've finally finished sorting the photos.
