Last of the Blacks Part I

i'll be leaving town for the next 2 days.  Going to Chincha located in the province of Ica. This weekend they are hosting their annual Festival Verano Negro.   According to many internet websites its the location of the last of the blacks of Peru.  The people are described as fun, entertaining, and flavorful.  Code language for Black/Minstrel.

But let's go back to last of the blacks...what does that mean? where did they go? and I thought I saw some here. More to come later!
