Jeremy Hobson: A major refinery for Chevron caught fire in California last night. The fire in Richmond, outside of San Francisco, has been extinguished, but one employee was injured at the plant and hundreds of area residents have gone to the hospital with breathing problems because of the smoke. And the fire could be bad news for drivers across the West, because one less refinery online is likely to mean higher gas prices.
