To see the early stirrings of NASCAR take a look at Robert Mitchum's 1958 film Thunder Road... When NASCAR abandons these roots it is no longer NASCAR. Its earliest champions spent time in Fed prison for hauling illegal {untaxed} alcohol.
My own roots go back to this rustic mountain time. The dialog may seem corny, but that is pretty much the way folks talked in those distant days. Robert Mitchum wrote, produced, wrote the music, starred in - everything in this cult film.
