It sounds like a Vulcan holiday or religious rite, but it is as I have been told the greatest holiday in Korea. It is a time for families to gather and celebrate family. We have a formal three day weekend starting on Friday, though I am planning to work at least 1/2 day Friday to be out with one of my units and will be pulling duty as the on call chaplain for the week. I was thinking of taking a tour out into the countryside, but this turned out to be a good weekend to pull duty as the travel office cancelled all tours. Supposedly the traffic here for this weekend would rival anything DC has to offer.
I'll have to see if anything pops up locally for celebration.
