Not a thing wrong with rednecks. I'll take a couple rednecks fighting alongside me over a couple city boys any day of the week. And you're right, location has nothing to do with it. I've met rednecks in every state I've been in, north and south of the Mason Dixon.
But yeah, they blow stuff up, hunt frogs in the golf club's water trap, find creative ways to pass the time at work, there are guns and shooting things in every episode, they eat some pretty tasty food, their women don't take any crap .... what's not to like?
