Buz forwarded a couple different images the other day.
This one is from the Los Angeles Times (pic #8) and shows a jeep among the auto train towards the internment camps in 1942. The caption to this picture indicates the trucks were stopped in the Mojave Desert on the way to the Manzanar Camp.
Driving this jeep is Earle Stanley Gardner, who was the writer of 80 Perry Mason Novels. Learn more about him here in this biography written by Jeff Marks.
