WA has some municipal fiber networks. In my county, you can get hooked up if you foot the bill to extend the network to your property and find a retail provider to service your account. There's an online map that shows where the fiber currently is, you'll save a bunch of money on fiber construction if you build near where it already is.
Depending on the area, you can't even get internet outside of full cities. I own a house that's a few miles outside of a small town in Oregon. When I moved up here from the bay area recently, I had to rent a second house in the nearest city 30 miles south because there is absolutely no terrestrial internet service even within the city limits of my ~700 person town.
