Patagonia Korea is sponsoring a Boulderers' Day near Jinan this weekend. I plan to be there (and can house a couple people in my tent with extra camping gear).

Logistics are hard without a car. I'll drive down Friday about 6:30 from Jochiwon (about an hour and a half south of Seoul) and leave Sunday afternoon. I am happy to help with logistics and pick up from nearby bus terminals. Check my profile and e-mail me if interested.
