I just drove that same route on Monday! At the state line going into Nevada is a great outlet shopping center if you are into that sort of thing. Otherwise you will pass the Calico ghost town but it is about 30 minutes from the freeway and will take up 2-3 hours of your trip. It is okay if you have kids with you but would not say it is a must see attraction. My best suggestion would be to get to Vegas as soon as you can because there is so much to see there now.
Good Luck in Vegas!
Well, there are lots if you love the desert...
No.not much out there.
