In 1960, Lange described her experience in an interview with the magazine Popular Photography. The photos that accompany the following account are captioned with Lange's field notes: "It was raining, the camera bags were packed, and I had on the seat beside me in the car the results of my long trip, the box
I was on my way and barely saw a crude sign with pointing arrow which flashed by at the side of the road, saying PEA-PICKERS CAMP. But out of the corner of my eye I did see it I didn't want to stop, and didn't. I didn't want to remember that I had seen it, so I drove on and ignored the summons. Then, accompanied by the rhythmic hum of the windshield wipers, arose an inner argument:
Dorothea, how about that camp back there? What is the situation back there?
Are you going back?
Nobody could ask this of you, now could they?
To turn back certainly is not necessary. Haven't you plenty if negatives already on this subject? Isn't this just one more if the same? Besides, if you take a camera out in this rain, you're just asking for trouble. Now be reasonable, etc. etc., etc.
Having well convinced myself for 20 miles that I could continue on, I did the opposite. Almost without realizing what I was doing I made a U-turn on the empty highway. I went back those 20 miles and turned off the highway at that sign, PEA-PICKERS CAMP.
The pea crop at Nipomo had frozen and there was no work for anybody. But I did not approach the tents and shelters of other stranded pea-pickers. It was not necessary; I knew I had recorded the essence of my assignment."
