I'm a bit confused...what do you mean they all relocated to the land of the gringos? South Florida hasn't been the "land of the gringos" since the 1960s. It was a swamp in the 50s...the Cubans built Miami.
Ball & Chain is AMAZING! It has been around since 1935...sooooooo much fun! You can always expect an older Cuban man to ask you to dance, even if you can't dance...they don't care!
