Ujust to quibble a bit. At night in high fog, we get 3 or 4 car pileups on the Grapevine. On the 10, in clear weather -- not gonna happen. And of course EVERY car has to burst into flame on contact.
Also, exit 43, near where I live, is 2 miles from exit 41, near Cal Poly Pomona. There are concrete walls and no drops at that section.
Otherwise, a great episode.
