To me, the sunset is beautiful because what it comes after is amazing too. I like the night, the starts and the moon and the sunset is one of the few things that makes me quiet to watch and contemplate. You don't need the perfect landscape to enjoy the sunset. The sunset it self makes any place amazing...the city, the beach, the country side. When I think about beauty, that's the first thing that it comes to my mind. (Those are some of my favorite pictures about some really nice trips)
