Yes, Goody, Lubbock is isolated. Backwards, maybe somewhat.
I think all descriptions fit Lubbock, the biggest little town, a college town, rich cotton farmers. When I was growing up we always referred to guys at Texas Tech as *advertiser censored* kickers, pardon my French. So it does have a background of being backwards. And while Texas Tech is not the premier university in the state like Texas A&M or University of Texas, it's become fairly progressive. And I think it is the main economic engine for the town, and I think it is like many towns in that the separation between the have and have not is pretty big. There are a lot of small farming communities around that feed the economic engine also, but probably not so much so everybody has a Walmart these days.
And I think the cotton has become a big deal since Levi's (or some major corporation) put together a coop and a manufacturing plant in Leveland which is near by. Don't quote me on this stuff; I'm very vague on the details. But in other words the cotton industry has the backing of a major corporation.
And it part of the Bible belt so you need to take that into consideration.
This is all my opinions and observations from a distant, even more backwards town. I have never lived there.
