10:03 a.m. subway

This was a rare opportunity to take a shot I've been wanting to take for a long time: all the doors between subway cars are open, and you can watch the train curve back and forth as it progresses along the track. Cool. My apologies for not blanking out all the faces, but I don't have the software for that. I hope I don't get sued for revealing someone's face. 

This is the 10:03 a.m. Line 3 train. I'll transfer to Line 9 in a moment, then arrive at Gimpo Airport by 11 a.m.
