Used to live in Tahoe, parents lived in Sly Park. So a lot of running back and forth on 50. At the chain inspection areas I have been asked if I was locked in to 4 wheel drive.
If you were not you probably would not be getting up to the guy very well anyway. They like to put the inspection point on an uphill straightaway where they can watch you approach. If you come up spinning all over and getting sideways your gonna get talked to and probably turned around.
Weird about not chaining up a Rubicon? I will have to go read the book some more.
Up in Soda Springs area they used to have locals on an R-4 restriction. That's where it was so bad you had to have a four wheel drive with all fours chained up. I don't think they even do that anymore they will just close it now.
Oh lookie what I found, strait from Caltrans.
