Sacramento to Redondo Beach, CA?

Sounds like a solid plan,getting in the So Cal area before dawn you should be fairly good with light traffic both Saturday and Sunday

Mostly trucks at those hours I used to be one of them.

I have lived in SoCal (LA and Orange counties) for 70 years and the traffic is always bad, except in the middle of the night. Watch out for the drunk drivers and you will be fine.

Or just dive into the daytime traffic and be prepared to spend an extra hour on the road. That's not so terrible. It's only this one time.

Think of those of us who deal with this every day of our lives. We just accept the traffic as the price of living in a place with beautiful weather and year- round camping. Mountains, deserts, beaches. Heaven on Earth, and 40 million people crammed into a crumbling freeway system.
