Any of these can happen to us, but we have been good so far.
Can we loose electricity? Yes. It has already happened to us. Two weeks without the electric.
Water we have never lost. But have learned you can loose city water. That happened to my daughter. So now we prepare for the just in case on that one.
We have never had to evacuate, but always ready to do so in hurricanes.
We do have family members that can be effected. We are prepared to take them in.
As for food, we are good with over a years supply of things I have canned and the long term foods I have.
We also have a whole house generator. But are prepared in case we ever loose natural gas. If that happens we can convert the generator over to propane. We would be ready to do so if need be.
