Thank you all for the good ideas, and tips on being realistic!
Midwest Michael-I see what you mean about the 101 and the 1 being the same in some parts. I was looking more at the northern part where they seemed to split off from each other. They looked like they were close enough to cross over between, but that is of course because on a map all the distances look small! But you are right..I'll need to stick to one road or the other-from the get go. Maybe I'll just see how early we can hit the road, and if early enough then take the PCH.
AZBuck-Thank you for the warning about Sunday and LA. We'll just try to leave very early on Sunday....and hope the traffic is light! I think the weekends aren't sooo bad in LA...
Judy-thank you for putting the options for day 1 so clearly for me. I think we'll probably end up zipping down the 5-unless we get up really early. Because I really want to spend a lot of time looking at the Redwoods. I didn't know Eureka was such an interesting town..I'm looking forward to seeing it now!!
