The day after tomorrow is korean traditional holiday "Seollal".
It is new year's day in the lunar calendar.
Most people plan to visit their home.
So there are rare scenes on highway because of traffic jam.
About 400 km from Seoul to Busan takes 12 hours surprizingly.
Fortunately, my situation is good.
Cause I will use an up line from Yeosu to Seoul inversely.
I think people have a basic instinct like a salmon going back home.
Perhaps there is a mom at home.
