Great question. I have about 20 gallons between the tank on the generator, plastic gas cans and if REALLY necessary I can siphon from two ATV's. Nobody knows if power plants will be compromised, or if credit card machines will go down. Some of the worst hurricanes and blizzards here in the northeast shut down the gas stations; so you might have to drive around to find one operational if the poop hits the fan.

Don't plan on running your generator 24 hours a day. Depending on the season, I typically shut off all the NON essential breakers (Air Conditioning, TV, furnace, etc) and make sure my well water pump charges up, and the fridge & freezers run off the generator for an hour. Under full load I might go though a gallon in 2 hours, but your mileage may vary. Fill your bathtub up with water so you can manually flush your toilet, just becareful if you have toddlers around.

VERY IMPORTANT ====> If you plan to run your own generator, you *MUST * shut off the main breaker from the street. If you don't you risk electrocuting a utility worker, and you may be overburdening the generator by powering your neighbor's houses. Lookup some how-to videos beforehand and take notes. Alternatively a friendly neighbor that also has a generator can probably help you (just listen for the sound).

The 100% Styrofoam shipping containers from Omaha Steaks work great if you have access to dry ice. If not a regular cooler is fine, but it may make the plastic brittle at -109°F . You have to keep them closed since the Dry Ice evaporates into Carbon Dioxide. Do NOT store Dry Ice in your house, it must be well ventilated as CO2 can suffocate you and your pets. 💀

Best of luck and stay safe Fred!
