This is an interesting read. I noticed also that Roscoe Bartlett, the rep running that hearing, moved entirely off the grid after retirement.
It's not especially noteworthy .. to those of us that also grew up away from large connected services - you have your own sewerage, generators, mail, drive | walk to town to pick things up.
Currently I'm "mostly" off grid - I have internet connection, a well, leach drains, solar + wind (electric) + wind (mechanical mill), etc and live in a rural community with a lot of people older than 60 who also grew up off grid.
Reads more like a self-written personal home page than an encyclopedia entry produced by independent volunteers.
