When I lived in South Korea - mountain climbing. strolls, coffee shops, hofs, finding restaurants that were out of the way - but had extremely good food. ride my bike along the river. art galleries, live music performances, karaoke (you have your own room with couches, a table, drinks, a big screen, etc. as compared to here where you have to sing in front of a crowd... i haven't found a korean styled karaoke place yet).
Where I'm at now - I'll go for a stroll at night, hang out in my backyard and thats about it lately. Missed out on horseback riding when I got sick. I'd like to find some good restaurants here, a decent spot to read, a good walking trail, etc. Movies are good as well.
