Pray that you are never in a situation that requires you to use everything in your emergency kit.
The idea of a kit, to me, is to have a range of assets which could apply to all of the situations I can imagine - with the flexibility to deal well with the situations I can't.
Car's in the water? You can get out but can't swim? Perhaps that emergency poncho could be tied to hold air and be a flotation device.
It would be a shame to see people scrap their preparedness kits just because the disasters that happened were different from the ones for which they prepared.
