I don't exactly know.  Did you know that salsa actually originated in New York in the mid-1970's?
Yes, but it actually originated in New York in the mid-1970s!
I love salsa dancing for exercise. It works up a sweat! Nice!  Salsa has it's origins in the Caribbean. It's a lot of fun. What else is interesting about it? The salsa's movements are derived from several other dances' forms, including Puerto Rican bomba and plena, Cuban Son, cha-cha-cha, mambo, and others! Very cool. So it's a mexture of all those?
The dance, along with the salsa music, originated in the mid-1970s in New York.
