Where is the most remote place you’ve ever been?

Have you ever been so far removed from civilization that it felt like a time warp? I remember driving through some backroads of rural South Carolina years ago, ended up 2 hours from the highway and there was NOTHING but cotton fields, abandoned/burned down farm buildings and literal dirt roads. Almost as if everyone fled the entire region in the 1960s. It felt eerie being so off the grid, knowing if anything happened I would have little chance of survival.

But even then I was probably at within 100 miles of a decent sized city.

What is the most remote place you’ve been to?

Flying over doesn’t count.
