Having seen Chile's problems with looting due to lack of food and basic order; how about a podcast about the necessity of having some of your food stores packed in a way for easy packing into a vehicle or even onto a go-bag. You could tie in the capabilities checklist and also talk about how it might be important to have foods that have "low visibility" when eating. (I don't want to be that one guy cooking a meal in a camp site when everyone else is hungry because they didn't bring anything.)

A nonspecific bug out location might also be a good topic here as well. Something different that having land or a cabin somewhere. Think laterally. Like a trailer, tent set up away from the crowd, a relatives house, closed/abandoned military site. When whole cities sink into the water, there's not much left to come back to.
