We used to have a semi-annual family exercise. twice a year (in the heat of summer and the cold of winter), om a friday afternoon, we turned off the electricity, gas, and water coming into our home. We turned it back on Sunday evening.
This is a great test of your preparedness. How will you preserve the food in the refrigerator and freezer? How will you cook your meals, flush the toilets, take care of personal hygiene, and keep warm or cool?
when you think you're ready, try this exercise. if there is anything you have overlooked, this exercise will find it.
Onward and upward,
