I would say even if you didn’t believe in prepping, it wouldn’t hurt to buy a couple of hundred pounds of rice/beans and such.
That’s sort of a start.
If you really want to find out, some night, before you go to bed, do the following:
Turn off your water heater
Turn OFF any and all gas appliances
Then go and hit your main power switch.
When you wake up in the cold and dark next morning, do you even have a flashlight near your bed?
I’m not pickin on ya, but livin in the northwest with ALOT of huge Doug firs around me, I lose power four or five times a year, so it takes some adapting and getting ready.
Just sayin!
