Do y'all have fiber at all? Most if not all of remote middle TN from Cookeville to Winchester has cheap FTTH. I live in unincorporated acreage, and was surprised they just came out this year to run a fiber line to my house. 57/mo for symmetrical gig. Goes up to 8, but that's a couple hundred.
That's how it is in Vegas presently: CenturyLink has fiber service but it's scattered around unpredictability, and in areas where it's not available it may never be.
Hopefully Google fiber (un)availability doesn't overlap too much, but I expect that it will.
