Last April, we got hit with F5 twisters that took our Nuke plant's main lines out.
Power was out for over a week.
Cash on hand was king, gas on hand and in the tanks was Queen, and having things like non perishable food, water, cast iron, a grill, and lump charcoal was vital.
I had to work 12 hour shifts at the PD but was amazed at the lines at the gas pumps that had generators trucked in. We try to keep over 1/2 a tank in both cars at all times and we have two 5 gallon steel safety cans (expensive but worth it) full of non ethanol gas with stabilizer stored at the house. We didn't sit in four and five hour gas lines like the rest of the city.
Being that ATMs were all out, having some cash on hand (I think we had about 150.00) was huge because one grocery store opened up on generator power and they weren't taking any payment but cash. My wife was able to buy ice (which was highly sought out city wide), water, and other goodies to get us through.
I filled the tub with water for flushing in case the water plant shut down (was close to happening but didn't).
Having a chainsaw ready to go was good for when the huge limb blew out of the neighbor's tree and I had to get it to the road.
A battery operated FM radio was nice to get updates for who had gas, where the ATMs were coming on line, curfew hours, etc. Having cast iron cookware (well seasoned) was nice for when my son wanted scrambled eggs and bacon and I made a huge pile of both on a flat skillet over lump charcoal.
And flashlights: always have loved little led flashlights and I had a ton of them. Probably 12 ready to go with lithium batts. Handed them out to my wife and son, put some Chapstick lids on a couple of AAA models to act as diffusers and we had plenty of light for nighttime navigation of the house.
We had plenty of ammo and knives too but there wasn't a need for them on such a short term outage. Most folks had a great time and the kids of the neighborhood got out and played like kids used to play.
Oh yeah, one more item came in handy. A power inverter in the car for charging the cellphones. At first, cell coverage was gone other than texting (which was spotty at best). Cell lines came on rather quickly and it was nice to have for communicating with the family as to what to bring home (ice, more water, food) and with out of town family worried about us.
Keep some cash on hand and some gas in your tanks and you are ahead of the pack. All the blade skills, camping knowledge, and other stuff is icing on the cake.
Duct tape, plastic sheeting, staple guns, some plywood and nails and you should be able to make general repairs that will make do.
It's all common sense and a little forethought/planning. We were doing well when the power came back on line although the cold showers were getting a bit tiresome.
