Radios, ice chests, swimming pools, and jugs of chlorine bleach all came in handy.
When he heard the hurricanes were coming, he froze water inside cheap freezer containers in his freezer. That were free blocks of ice that he didn't have to buy, and blocks of ice take longer to melt than ice cubes. (I actually keep a few 2-liter pop bottles full of frozen water in my freezer at all times. They are great to use in ice chests, and when the ice melts, the water is contained in the bottles and doesn't get all over your food.)
He gives recommendations for various types of good and not so good gasoline containers. I agree with him, the nozzle is not as important as just buying a Superfunnel (about $2 each from an auto supply store. It is a big funnel with a VERY long tube at the bottom, which is small enough to fit in the opening of the gas tank). You can fill your gas tank much easier by pouring the gasoline from a gas can into the Super Funnel than out of the gas can's long nozzle. They are never designed right.
