had a nice day, visiting hightest point in Seoul, the N-Seoul Tower, got the cable car up to the summit, although Owen said he walked it in the summer, which is very impressive.
cable car takes you through the wooded hillside of the mountain, unfortunately a bit misty today, so not clear views of Seoul, but could make out river through the mist and city from the top. Impressive views, even through the mist.

We then went to island in middle of the Han river, nice place for biking.
