I gave a lesson at church today about being prepared. One of the things I talked about was having a 72-hour kit in your car. Here in California, we live in our cars so it makes sense to have a car kit. I keep mine in a regular backpack with padded straps.
Since So Cal is very hot, I recommend changing out the food every six months. Try eating only what is in the food packs for 3 days. You may want to fine tune what you eat. If you have kids, let them have it every 6 months, it will be like camping for them.
