Living in earthquake land as we in CA do, we are suggested to carry enough water (emergency rationing applies) for 5 days for all members of your travelling group. This water is packaged in individual foil packets. Space blankets, one for each seat, are available at many types of stores, are a good idea to store in your Odyssey too.
Food is another story, if you are doing any type of camping or car camping you will have supplies for that, I hope! Nutrition bars that are sealed and dated are also available, although I must say that my wife and I taste tested some once they had expired and sorry to report that we both agreed that starvation would have to really be close to eat one of these again. We did not replace them. Another item gaining fame is a so called life hammer, used to break a window or windshield in the event of entrapment, these also have a cutting blade on them in case you are locked into and cannot get out of your seatbelt. These items are all easily found online.
There is nothing wrong or paranoid about planning for trouble. It's a motto for a reason: BE PREPARED
