All a matter of perspective, I suppose. I'd call that the middle of nowhere, but I've always lived either in a medium-sized (>1 million people) city or its suburbs.
In particular it doesn't seem to have public transport at _all_, at least per Google Maps; I'd consider anywhere where your only option to get to a city was to drive to be serious middle of nowhere, though I gather that this is a more common condition in the US.
See, this in and of itself is an interesting perspective. The US only has 9-ish cities with a population over 1 million (according to Wikipedia and going by the population within city limits, if you go by "urban area" it's more like 45), so I would call a city of over a million people to be a large city, pretty definitively. But then, I never spent much time in million-plus-person cities growing up, so I'm just not accustomed to thinking about them that way. To me a medium-sized city starts around 500,000 people.
To provide another possible perspective, this is of course peanuts compared to China, which has 11 cities with populations over 10,000,000 and over 100 cities with populations over 1,000,000 (again, Wikipedia numbers) and a fairly urbanized population as a whole. That's a country where I could see someone calling a 1,000,000-person city "medium-sized," and if anything they might be on the low-end.
