I was excited to see the South Korean flag in my Facebook feed this morning. My son-in-laws family immigrated to the US from South Korea when he was 7 and my four granddaughters are half Korean. I am going to assume there is no prejudice in the question but rather you are wondering "why?" and "what's the attraction to Koreans?" In fact, there are books about the Camino written in languages all around the world. Korea has a large, faithful Catholic population and there have been some very popular and inspirational books written in Korean about the Camino and it is my understanding there is a strong online network of people interested in the Camino.
PS: I know North Korea is in the news a lot these days, and I am sure most people reading this know this...but just to be sure, I am going to say it anyway...
Despite being just a DMZ away, the cultures of N and S Koreas are worlds apart. And much like the immediate post-war Germany, families are split on both sides of the border. Hopefully someone from Korea will post also to fill in or correct whatever facts I may have missed.
