Thanks for a great link, Joe.
My favorite description of the weather follows (though don't all Camaros shake?):
Jerad Voight in the No. 77 Chevrolet Camaro SS RS who came 12th in class, 108th overall, said it was raining up to the Ws, a set of switchbacks that begins seven miles into the race, then it was fog so bad he couldn't see more than 60 feet, "After the fog it was snow, Devil's playground was hail, just past that it was rain and then heavy winds on the last section – I could feel it shaking the car." When we asked what was the weather report he was given at the start line, he laughed and told us, "They said there was a sprinkle at Engineer's Corner."
