Jumping ship in Incheon, Korea

My connecting flight to Japan is delayed! 12 hours maybe 24 who knows! A bit restless and ready to hit the road I made the decision to ditch the flight and pedal out of the airport. I am now in the north of the country and am full of options. I really have no idea where I am, in terms of where in the country the Incheon airport is as well as how far I am from Busan. From what I remember south Korea is not that big. Well, here we go; another country, language and so many new customs. It all begins right here and now. My east Asian adventures begin in Incheon!
