I'm living in Sanbon, Gunpo City, outside of Seoul.

Does anybody have recommendations for a local HDGD school? I am willing to subway it to Seoul on a regular basis if necessary. It's only half an hour... Daehan haidonggumdo is preferred.

There's a 90 minute class at Seoul Foreign School on Monday and Wednesday afternoons at 3:00, but it's not particularly close to any subway stations, so you'd have to cop a short cab ride. Except fpr yours truly, the "scholars" are all primary and middle school students. The teacher also has a dojang just north of Seoul National Univ Station, which would be much closer to your current location, where he has classes most evenings. Ialso generally work out there with him on weekends. He's a youngster (at least from my perspective) but he's been at it for going on 20 years and is quite talented and personable.
