There’s a sharp divide between city-dwelling folk and those making up the (by and large) shrinking population in rural areas. My first trip to the second largest city in Korea, Busan, was a bit of an eye opener. When the bus first dropped me off, I saw it as the complete antithesis of Seoul: abundant green, no sign of high-rises, and not much of a crowd. The deception is in the topography: Busan, with almost four million people, is comprised of districts, almost all separated by mountains and bodies of water. And with the subway reaching to the outskirts in Nopo-dong, I knew I wasn’t in Kansas anymore.
