My brother is in Korea to teach english for a year. A few days ago he was told exactly where he'll be teaching, Jeongseon, Kangwon-do province, South Korea. Sensing a challenge, I went ahead and tracked down this moutnain town.
The image on the left is a Google Earth image of the area around Jeongseon. It's a mountainous area - the town appears to be jammed in between 1000 meter peaks at a 180 degree bend in the river (what river?). It also appears to be small - it's smaller than 2 miles from end to end. If you'd like to find Jeongseon, go to 37° 22'36.52" N, 128° 39'54.46" E.
Here's the most detailed map I can find of Jeongseon. It's pretty much in the middle of the map. Unless you can find one nearer, the closest city I can find to Jeongseon for weather reports is Yongwol, about 25 miles away.
Oh, and even though you're probably hip to this tip, Adam should be posting stuff about Jeongseon & more at Skorea.
