Bad news for the CA central Valley

And California is the tail that wags the dog for several other states including Colorado when it comes to emission laws, I heard a rumor that collectors plated cars in Colorado may soon have to pass emissions test because the brain trust feels that older cars are causing the brown cloud over Denver. Couldn't be the tons(and I mean TONS) of sand, salt and magnesium chloride that is spread on the roads making dust, could it? Bastards!
