Deagu is a friendly little city up in the hills. Visited the Arbaretum, built on land reclaimed from a landfill dump. It certainly  is a pleasant place to while away a few hours even if you are accompanied by most of the population. There was s flower exhibition on which may explain the crowds. Believe me there is nothing you can't make out of a few potted plants. 

Getting around should be easy on the subway, although I did manage to head in the wrong direction,twice. So annoying when you count the stops and when you get to zero you are no where near where you think you are.

Price is very cheap, around 1200 won or about 50p. Someone on the train asked me why the London subway is so expensive. Good question.
