The whole Bay Area is "Too Hard For the Radio," that's the excuse every Bay rapper has been using for years. It don't apply to Yuk because he ALREADY has a mainstream following. He has people as young as me (Who was six when 5 on it dropped) that are following his shit. C-Bo doesn't have the production behind him that Yuk has. Sacramento rappers in general just don't have enough support to hit mainstream, buy Yuk does and already has.
