I'm amazed at the number of non California resident POG members spouting off on what's good or bad conduct to use when visiting our state. On the above question, it's one of safety first. You are not allowed to cross the double yellow line morraly or by law. Antics like that will get you and others killed. There are many roads in California that cannot be brought up to freeway status. The mountainous terrain dictates what degree these roads can be advanced to. Come here and enjoy yourselves. View the beauty, obey the law and we'll pay the taxes. We will do the same for you when we are guests of your states. Thanks for your considerations.
