This reminds me of something I saw on a backpacking blog sometime last year. Project Remote, a family that's finding and hiking to all the "most remote" place in each state of the USA. Here's some of the statistics:

The most surprising one to me is: Least Remote: Kansas (0.8 miles from a road).
As someone who lives in the very densely populated greater Boston area, Kansas doesn't exactly strike me as a prime candidate for not being able to get away from roads.
Their website seems to have been commandeered by some Indonesian online casino scam thing in late 2024 and is now offline. I'm unsure of the ongoing state of the project.
