I keep my gas tanks full at all times, but I don't think it would do us much good to try and evacuate in case of a nuclear disaster. I have 3 nuclear power plants near where I live, The only direction for us to leave would be to go south. I have prepared a shelter in place room in my bedroom, it has a private bath in it.I have oil lamps, plenty of lamp oil, candles, batteries, flashlights, radio, battery operated tv. and enough foods and drinks stored in totes in the closet to last 4 weeks.
I have also purchase the good ole duct tape, plastic sheeting, heavy sheets of cardboard and sheets of ply wood. I also have on hand dark garbage bags, a 5 gallon bucket with tight fitting lid (potty purposes)a camp stove, with fuel, toilet paper etc......
