I met my friend Kyoungmin today, visited Namsan taking the straightforward route up and then the interesting route down. We had no idea where we were when we finally got to the bottom haha, but sure enough we walked for a while and found a bus stop. While riding the bus, we passed by this park and I saw a girl with a keytar on a stage, so we went.
I have some more pictures of the whole thing at the following link, because it seems Blogspot limits the amount of photos I can upload. If you want the fullsize image of anything, just comment with your email and let me know what you want (I have full size of all the pictures in the Facebook album too):
