Well, I've not spent much time in Muskogee. I suspect it's a little rougher than it was in Merle's day, but probably not far off.
In my small town, other than a few meth heads running around, I'd say the song rings mostly true for us. I'm sure you meant it as a joke, but I think the overall theme of this song is still in line with the mindset of most rural folks in this part of the world. Family oriented, patriotic, church going, respectful, tough, resourceful, hard working individuals still dominate in these parts. You know, rednecks. I can't count how many transplants, visitors, and folks I've run into while travelling have told me the Okies are the nicest people they've ever encountered. I mean look at 6PC. He's such a nice guy and Okie born.
