Hey there,
I'm Hilary, I've been living in Busan since December 2010 and in Korea since September 2009.
I'm living in Saha-gu now, all the way near Tadaepo beach. It can feel a little slow and isolated compared to the more exciting areas of Nampo, Seomyeon, PNU, Haeundae and Kyungsung. But it need not be this way! If you live in Saha, and are looking for people in your area to chill with during the week, share taxi cabs on the weekends, etc, post here. If you're on Facebook, we made a group you are also welcomed to join:

(Of course, folks not from Saha are welcome too, it's just...usually Saha outsiders don't want to travel to ALL THE WAY to our area ;) )
Cheers!
