Good topic, @
Nyboy . We live in hurricane country and sometimes go for weeks with no power. I think the shortest was a week and the longest was over 4 weeks. Just plan on the freezer thawing. Plan on eating everything in it and calling all the neighbors that might be hungry. Honestly, we generally have a housefull of people anyway. I have hand saws, axes, chain saws and other things to reduce fallen trees to BBQ wood.

I keep what we call coal oil lamps (and you oughta hear this Texas/Southern accent slaughter the pronunciation cole-AWL and I manage to make the cole into 2 syllables) or kerosene lamps and I can walk in pitch blackness to the box of matches and lamp to get it lit.
Forget the stores. They get wiped out-clean empty. Then when power is restored, it is a week or two before they can open back up. ALL the cold/frozen food is melted, soured, rotten, stinky, thrown out. Then they have to clean all the cold cases and restock. I think everyone should experience walking back into a grocery store after weeks of nothing just for the grateful feeling it gives you. It is a sacred kind of quiet, like walking into a church. People all ask how each other is and how did they weather the storm. The shelves are still mostly bare, those dozen packages of meat are dwarfed by the empty expanse of cold case. It's weird.
Food? I have squirrel DNA. No, I don't bury it in the backyard, but the pantry is packed. I have buckets of rice, beans, 2 kinds of wheat, quinoa and sugar. I have 1/2 gallon canning jars that I use for dry goods storage. I have jars of jelly, preserves, and vegetables from the garden. Before a storm, I go buy several big plastic trash cans with lids and fill them up with water, along with every receptacle I can lay hands on. We eat darn good around here. I have made flour tortillas over a fire in the back yard and they were scarfed up faster than I could cook them. I think we could last for several months, easy. Might get tired of rice and beans, but what the heck. Those chickens would start looking mighty good. And I always have a garden, year around. You know you can eat pretty good if the garden is in.
Hurricane Rita came 3 weeks after hurricane Katrina obliterated New Orleans. Houston evacuated. Millions of people fled. A 2 hour trip from Houston took 22-27 hours and people ran out of gas. It was over 100* and several people died in the heat. We were covered up by people that were supposed to go past our town to shelter towns further inland, but they didn't make it. We opened up our schools and churches. I spent a few nights at the elementary school behind our house and a couple of nights at our church. We ran out of food at church, so I went scrounging. A local fast food restaurant opened up the freezer to me, since it was melting anyway. I went back to the church with a truck load of semi frozen food. They got what they wanted and I distributed the rest around the neighborhood.
SHTF situations happen. You just deal with it.
