Hmmmm... with Laws like this, is it no wonder...

I bet the number of un-registered and uninsured cars in the state of Californica exceeds the entire population of cars in the three states it borders. I further betcha if we got rid of those cars our air quality would benefit 1,000,000 times more than enforcing some stupid sticker on one cat over another on a handful of older cars.
