Keith Rawson has written an excellent article over at Lit Reactor for those who are yet to hitch-hike along the rutted gravel roads of some exceptional writing.
It's more than just meth labs and single wides: A rural noir primer; takes a look at some of the writers plying their trade in the backwoods hollers and hill country shacks of rural America.
