"I was totin' my pack along the dusty Winnemucca road,
When along came a semi with a high an' canvas-covered load.
"If you're goin' to Winnemucca, Mack, with me you can ride."
And so I climbed into the cab and then I settled down inside.
He asked me if I'd seen a road with so much dust and sand.
And I said, "Listen, I've traveled every road in this here land!" - J Cash
I think there are ways to do it and people who can do it - in such a way as to minimize the risks.
That said, if you are seeking and I quote: the ultimate antithesis of the luxury travel we enjoy so much - may I suggest you head to Mexico to document the train hoppers making their way from Central America through Mexico, on their way to the U.S. for the mere opportunity to bus a dinner table or mow a lawn.
The story of these people seems quite compelling to me.
