I like this tourist attraction which let me go straight on and on and just enjoy sightseeing. It is said to function as commercial waterways as well, but only ships I saw were just for leisure traveling.... 여기도 주로 밤에만 화물선들 다니고 그러는 건가... =ㅅ=a... Anyway, the name! I didnt know origin of it, but thanks to wikipedia, 하하하하하, now I know it comes from Latin Sequana which means "sacred." 이름도 예쁘기도 하지~ : )
