The reason we were able to do this was the Colorful Daegu Festival. The yearly festival hosts art vendors, musical performances, and a big parade as well. All sorts of quirky and creative things are going on for the whole weekend.
Some people had so much fun they couldn't even stay awake. A nice little Saturday evening blackout in the subway station is a nice way to say "I'm finished for tonight." I thought the use of the soju (the Korean alcohol of choice) bottle as a pillow was as creative and hilarious as it was sad.
