One week, in my own house. We were part of the ones that lost power during ‘snowmageddon’ in the south a couple years back. Thankfully due to some light prep I’d done during the initial COVID outbreak I had plenty of canned meals for the fam and a nice butane cooking stove. Hardest part was keeping the house warm but we basically had some candles and plenty of blankets. Honestly could have been really bad, but looking back it was a nice little respite.
