Mind you there's a hefty tax surcharge on Diesel that could easily be lowered if the trucking economy was that important to states like California. Two years ago Diesel was at 8$ when it was 4 everywhere else, last year 9$, 5-6 in most other states. Now 10$? Haven't been there lately but it's still at 6 in MO/AR. It's not the oil price that's the problem with the Diesel price.
