One of the joys of my style of fieldwork--two weeks or so at a time--is that I have to figure out what to do with the weekends in between. I can't expect interview subjects to meet with me on the weekend, soooooo I have to find something to do. During my first trip to South Korea five years ago, I spent one of the weekend days during a DMZ tour--a tour bus took us to various sites along the DMZ including going into one tunnel that the North Koreans had dug. Very cool! This time? I decided to go to Busan.
