And we have to add to all that FOOD PRESERVATION! Can anyone "can" vegetables in mason jars? My mom and sister could. How about make the sausage, or pemican, or smoke or dry meats, or salt a ham? All the Foxfire books would get taken out and reread, for sure. Wood heat? You betcha, but better buy or weld up your own in advance as a welder might not run, don't know.
Communities should have hardened electrical pumps for the water system, and at least one emergency vehicle so equipped, IMO. Old Dearborn heaters with the correct orifice could use propane.
It goes on and on. Thing is, my uncle Tim has never quit living by wood heat, etc., etc. He wouldn't even miss a beat. He has huge water catchment to grow his garden, well water, pond water, creek water, nearby lake, good neighbors and lots of firepower. His son is a Moorhead mechanical genius. I'm definitely going to his place!
