What are some of the most isolated places in the United States with good broadband access?

I am considering moving away from the cities to a more rural lifestyle, but I still need my broadband. Ideally, I'd like somewhere an hour or so from the nearest outpost of civilization where I could build a small cabin on my own land. If internet access weren't a concern, the answer would be rural Alaska. How close can I get to that without giving up my connection?

In Alberta (that's in Canada) the government has finished running fiber to every government building in the province. (So every school in every small town is a fiber terminal. If a business wants to use that fiber to set up a WISP, (wireless ISP) they can pay to access the fibre. I live half an hour from Edmonton, and there are at three wireless companies competing for my packets. However, this is certainly not the most isolated place. But, Alberta has no end of wilderness.
