Thank you AMAC for the insight on the origin of the word "hillbilly". The word really came into vogue during the 20's and 30's during the heyday of the "moonshiners". NASCAR had it's origin from that period of American history also. The bootleggers would "soup" up their cars to out run the laws. Two movies that really depicted that era were, Lawless and Thunder Road.
Do you happen to have any information on the term, "redneck"? Thanks for sharing.

A slang term, usually for a rural white southerner who is politically conservative, racist, and a religious fundamentalist (see fundamentalism). This term is generally considered offensive. It originated in reference to agricultural workers, alluding to how the back of a person's neck will be burned by the sun if he works long hours in the fields.
