If you are on a well and septic, as I am, when you are without power, it's sorta a big deal. This is why I have a 14kw standby generator.
When Sandy hit, my basement would have flooded without the generator.
Some neighbors went 7+ days over a number of storms in the past 10 years. Just throwing a bag of ice in your fridge doesn't cut it. Putting it in a cooler with some, you can keep some stuff but after about day 5, it's a soggy mess. You end up losing most of your frozen stuff and some of your refrigerated stuff. In the winter, you can usually put food outside, but hurricanes and ice storms come in the fall and early winter(where it doesn't get freezer cold) tend to be what takes out the power
You can't flush the toilet. I've collected water outside for a flush, but unless you have a direct source, it's an issue You can't take a shower, even a cold shower.
Eventually even your LED lantern's or coleman lanterns run out.
I have moved temporarily to a hotel for a few days, fortunately the one time I did this I found one near work that had a generator(everywhere else was out). That virtually guarantees you lose the entire fridge/freezer.
Yes, I will survive. No I don't want to shit in the woods and not shower. This is why I have a home.
