Last week was the Chuseok holiday (basically Korean thanksgiving) and my friend and I went to the southern coastal city of Busan for vacation. Everyone travels home to spend the holiday with their families, so reserving bus/train tickets can be a nightmare. We managed to get tickets for one of the slower trains, which was a 4 hour trip. I can't really complain because I read a whole book on the train - Malice by Keigo Higashino, which I recommend.
