Power failure in GA is not bizarre, so no excuse not having a working generator (fuel etc included).
Freezing temperatures are not unusual in GA, so alternate heat sourcing is not unreasonable.
Having a pump, or at least a cup on a string (you’d be surprised how few have a suitable string), is vital if you’re expecting to use a well.
A generator will be needed for communications, serious light, and house-preserving cooling. (Many homes will internally tear themselves apart if not kept dry and cool inside.)
Whole point is that some people think they’re prepared, only to find that whatever their plan they lack something critical. Got a year’s worth of canned food, wise guy? You have a can opener that’s going to survive a year’s worth of cans?
I have two heavy duty regular type can openers and probably 8 military can openers. With a little practice, the military one works just fine. The reason I don't know exactly how many military openers I have left, I gave them as Christmas presents to some family members and gave each one a metal “spork”. I carry one of the metal sporks and one of the military can openers and a small authentic Swiss army knife in my purse. In my car I have a four way silcock key to open a water line on the side of a building. Everyone should have a four way silcock key in their car.
