I'm taking my '49 Buick to the desert lake beds of Southern Calif. (e.g., El Mirage Dry lake, Superior Dry lake), Barstow, Mojave, etc. in a few weeks.
I'm a little apprehensive about the Grapevine (Hwy 5), and I have never driven Highway 58 from Bakersfield.
Going to that area in a newer car, over recent years, I've taken Hwy 5 southbound, up the Grapevine, and then to Hwy 138 East and so on.
If I want to avoid the steep Grapevine, how's the drive along Hwy 5, to 46 East, to 99 South, and then to 58 West? Any very steep hills I need to worry about? This old car has its stock brakes. Although recently adjusted, I don't want to go flyin' off any cliffs.
