A few years ago, my wife and I lived in the midwest. Specifically, we were in south-western Iowa. That was a real experience on it's own, but a story for another thread. Anyway, one of the idiosynchracies of the area seemed to be that when people danced the "cha-cha", it was a couples formation dance! Basically, it was a line dance that people did as a couple. Imagine my surprize when my partner and I heard some cha-cha music, went to go dance one, and were pushed off the floor by a huge mob of format cha-cha couples! Very interesting! Just wondering if anyone else has more experience with this. Is it common in the midwest, or elsewhere in the US? Are there other dances danced like this, danced in couples line-dance formation? etc.
