As we all know, the grove street gang in Gta San Andreas is the Crips gang in real life. However, i started to think that originally the grove street families were meant to be the 187 gang.
The 187 is a gang in Los Angelos, it's colour is black. And looking to old magazines and trailers, we all know that beta Ryder and Sweet used to wear black, whilce Big Smoke wears white( which means that he didn't want to represent the grove, and makes a betrayl obvious) and also by looking to cutscene.img file, we can find a lot of old grove street skins that ressembles to black or grey. This makes me think that the grove was meant to the One Eighty Seven gang itl.
Sorry for my bad english tho, lemme know what you think about this
