In your post in the CT forum, you said you were going to Temecula, CA, which is about 75 miles
south of LA. How far west on I-80 were you thinking of driving ? Since it would take you to San Francisco, CA, which is 500 miles
north of Temecula.
ISTM a more southern route such as this would be preferable. Avoiding both I-80 thru Wyoming, and I-70 thru Colorado. And the I-80 congestion around Chicago.
