As a Dominican American, I could not disagree more with the Justice Sotomayor, where I do agree is that DR's can follow to any type of music.
My salsa instructor is an AfroAmerican who can out salsa anyone. I always thought I knew how to dance salsa, when in reality I was doing cumbia moves. I was taught how to dance on 1 (Cuban) and on 2, as my instructor always said, "Salsa is about making the girl look good, not you".
Now that I know how to dance salsa, its hard to find a girl in DR who "truly" knows how to dance salsa. I noticed that when a good salsa song comes on, they leave the dance floor and just sing the song.
I'll be in DR in a month, drinks on me women, if you can dance salsa.
My 2 cents.
