It's very popular, the dancing in these parts of the world. I would say, more popular than it is in USA. There is surely dancing in USA, but it is different. It is kinda more free-flow. The USA has more freedom and experimentation.
So in South America, or if you prefer, Latin America, the dancing is more traditional. It is structured. and they dance in a more serious way, as to what the activity means. In USa, it's become just another thing to do. It has no structure or tradition. I mean, there is some, there are always exceptions.
