When we were hit by a bad storm about 5 years ago, we were without electricity for 1 week.
We had a built-in propane stove in the old trailer out back...but had to climb over several downed oak trees to get to it.
We now have a big Coleman generator to kick into service if we need electricity. We have a stove out in the teardrop we can bring in the house. For water we have both a well and "city" water.
For heat, we have a large ventless fireplace in the living room...will heat most of the house if need be.
In hot weather, we have lots of fans....some 12 volt.
And of course assorted camping gear... Coleman shower, porta-potti... lanterns... as long at the fuels are available!
I think we could get by pretty good for awhile...and probably truly appreciate what gear we have!
