What about South Oakland?

The burning question now is, why doesn’t Oakland have a region designated as South? Lots of people we have talked to have commented on the fact that East Oakland is geographically situated in the southern area of the city, while the Oakland Hills constitute due east. So, what about it? Why no South Oakland? We were amazed and shocked, that as we rode towards downtown from Fruitvale, that we encountered a CalTans sign for…SOUTH OAKLAND!!!
