In June I led my friends on an expedition to find an abandoned theme park in the centre of Seoul. On a blazing hot day we started off with an adventurer's lunch - a McDonalds. True hearty food for an afternoon of searching. We searched and walked aimlessly with a direction of vague north until we found a park. The inside the park after following a stream we discovered the theme park. To find it full ... of children and English speaking edu-tainers. Not so abandoned.
Based around the Alice in Wonderland theme - it still was a pretty surreal thing to find in the middle of a big city.
