No, parent cited _business_ Gigabit. You're talking about retail consumer connectivity. Totally different things. Based on my deep knowledge of connectivity options here in rural Montana parent is correct: there's lit fiber all over the place (certainly to all cell towers) and various telcos will trench up to 5km from any of those pops, for a price. So a business looking to acquire Gigabit connectivity can readily access it. Ask your parents to call the ILEC business sales guy and see what happens. They'll need $5k/mo budget for transit fees and be willing to sign a 3-5 year contract.
