We've been weeks without power.
Cooking the food isn't usually a problem.
There is always the charcoal grill and in the winter the woodstove is usually fired up.
Keeping the frozen stuff frozen is the hardest part.
The generator works but it's an annoyance and the expense adds up.
Guess I need to look into canning.
Hoarding is buying more then you'll use or need.
(Well except for toilet paper that is.)
Being prepared for the unexpected and taking advantage of sales is just common sense and the way I was raised.
