Public transportation promotion day

One day a year, Seoul provides free public transportation in the morning. Since I can't read the signs, I don't necessarily know when it will be, although since there are new temporary signs posted on the bus stop, I do assume that something out of the ordinary will be happening. This is the street on Tuesday morning -- they put barricades along the street and only allowed buses down the center. To catch the bus, I had to walk out into the middle of the street and hope that my bus didn't listen to the policeman with the whistle and not stop at the stop. Fortunately, he ignored the frantically whistling policeman and stopped long enough for several of us to get on.

The weird thing about the free transportation day is the lack of beeping and the scan card again message (that's what I assume it says). When you get on the bus, you have to scan your T-Money card. And if you get the X, you have to try again. And when you scan your card, the amount remaining appears on the screen and it says "Kansahamnida". But when they turn off the machines, there's no beeping or voices saying "kansahamnida", so it's almost like the Twilight Zone, in an alternate universe.
