The whole reason my family decided to move here from San Jose,CA was pretty much because we got word of Cali falling into the ocean. Memphis is like San Francisco and Nashville is a wannabe Los Angeles and Knoxville is like a Sacto/Oakland combo. I don't know how far above sea level Tenne is, though. This place isn't as redneck as most people think it is. You might run into one or two at most.
In my experience, San Jose California can actually be pretty damn redneck (depending what part of town you wander into!) :-P
