There was nothing else to do but escape the horrible life on the plains during the depression. Farmers didn't know it but when they plowed up the grass and the drought came the soil blew away and there was no way to farm any more. Farmers who left the dust bowl states had no money to buy or train tickets and they were illegally hopping on trains. BY 1940 more than 2.5 million people had fled the regions and went to California.
sleeping alone was dangerous. You could be robbed, beaten or even killed. It was lonely riding the rails. Food was hard to find whenever I could I would try to find a hobo jungle. There I could get something to eat, sleep safely and have people to talk to. People turn to the road to see of they can make luck some where else.
