Vomit and life jackets, that should say it all. Two weekends ago I was on the ferry back from Geomundo, and the winds were 45 km/hr, which made for some pretty rough seas. It was a violent and distressing ride, to put it mildly. The boat should not have been out in those seas, and we almost ran out of barf bags. Koreans all around me were weeping, cowering, and puking. It was like being in a plane crash...for 2 hours. The life jackets and air rosaries did little to comfort me.
