My family and I have done this quite a few times....., several years ago we had a major ice storm hit and were without electricity for over two weeks. No heat except the cooking stove that was butane at the time. There was no going anywhere with ice as thick as it was. To top that off, I had an extra 5 people in my house iced in, so that was a total of 9 of us. We had to haul water, which we did in 5 gallon buckets loaded in a red wagon being pulled by manpower. (we lived off a well, so we had a 500 yard pull from a neighbor with city water) Our food of choice was what I had stocked, mostly beans, and canned food, and what meat was in the freezer. So soup or chili it was...we lighted with candles, played board games by candle light to hold off the boredom, heated water for spit baths.
And several times a year, it seems we'll have a bad storm that throws the electricity off for days...and daysssss...and daysssss. The last time was last summer, we were without for over a week...and it was over 100 degrees in the daytime. No cooking indoors for that reason, but also because of a glass top stove which is to my disadvantage. Yes, we were miserable...hotter and more humid than hell, no sleeping at night because of the heat.
But, we also camp that way. We usually camp during deer season, there isn't any electricity, no bathrooms..we rough it for a week or so. If you eat, its either already prepared or cooked over a fire, you wash up in the creek, and sleep in a tent. For years, I have cooked Thanksgiving dinner over an open fire...everything...it's cheating if ya don't...LOL
So...I've done it....
