You're lucky to be living in Gwangju. I live in a decrepit, old town. It has its charms, but I find I am spending more time in my apartment working on little projects instead of heading out to Gwangju or the big cities. When I do head there, I go exploring the little shops, and restaurants. I'll sometimes eat street vendor food if I am not particularly worried about what I am eating.
There's too much to do to get bored! :) :) :) :) :)
