We did a lot of hiking.
When you visit Korea, it is easy to understand what Koreans would develop martial arts based on kicking. It's true that when in Korea, I do a lot of walking, up and down hills. Legs get strong in an environment like that. I think that all Korean martial arts practitioners should visit Korea at least once in their life to experience the culture and the lifestyle of the people. It definitely adds something. Korea is very safe too. You never feel like there is any danger from a physical assault or even a robbery, or at least I don't. I have seen fights though, in bars and even kids outside, but those look more like mutual affrays between two willing and consenting participants than anything else.
