Intervention on A&E isn't just rednecks, but I have seen an influx of rednecky-types on the channel. A lot of the folks on Hoarders fit the bill.
My sister goes to university in Memphis and ran across the cops from the Memphis division of A&E's The First 48 by the Mississippi River a few months ago. Looked like they were looking for clues pertaining to a crime, so she didn't want to bother them.
