Sangdangsanseong Fortress
Today (Sunday) I went with 10 other Fellows to visit the historical Sangdangsanseong (Sangdang Mountain Fortress), in Cheongju. We walked the whole length of it (around 4 km). The gang were Merle, Pia, Josh, Ulrich and his wife, Kim, Doug, Ionut, Sergey, and Matt.
Wonderful sightseeing trip.
