As a kid I lived what people say is off grid. My family were loggers and my dad owned a logging camp on Sonora Island. At that time there was no solar panels or even gas generators. We had coal oil lanterns, a battery powered radio which we used sparingly to listen to the news and my mom had a gas powered ringer washer. We had a pipe running from the creek for water. It wasn't that we were poor, we also had a yacht and my dad had a new car every year for when we went to town, it was just what was available at the time. We had a cookhouse and a bunkhouse for the men. My grandpa also had a small house and one of the men and his wife also had a house. The houses were what were called skid shacks as they could float on their logs to a new location and then skidded up the bank to their new spot by a donkey. Not that kind of donkey, this kind.
As a kid I never thought it was anything out of the ordinary but yeah it could get boring having no friends other than my sisters and brother.
The only way in and out was by boat or sea plane. I also lived in similar circumstances on Texada Island and Samuel Island. What I remember the most was the great salmon fishing (what it used to be), swimming, hiking and berry picking. I ate so much sea food that I don't go out of way to eat much anymore.
To choose that way of life, I guess is okay but why limit yourself. I'm isolated enough for my liking. At one time there were lots of small communities up and down the coast that have now been abandoned.
