Welcome to the forum, please stick around.

As the others have said, your question asks something only you can answer. The answer depdns on what YOU and those you will be taking care of will need. Those needs can really only be known after they arise. Preparing is trying to anticipate what your needs might be.

So, you need to examine the people for whom your are selecting. How much food and water and other supplies do they need? Don't forget to think about hygeine, medical supplies, with food think of both nutrition (vitamins, minerals, etc.) and calories, shelter, clothing, etc.

You want things to be both enough and flexible. For example, my BOB has a pair of golf rain pants. Water repellent enough to keep me dry, light enough to wear in summer, warm enough for winter if I put a pair of thermals on underneath.

You also need to examine what kind of events could cause you to go to your preparedness supplies. What are the kinds of things that might happen in your area? What are the needs that might arise when those events do arise? How much warnign time will you have if one happens? All of these answers may change your preparations. Most people tend to think of the worst possible events, because if you are prepared for the worst, then you are also prepared for lesser events.

You also need to consider your capabilities. I know of no one who is going to carry a weeks worth of food and water on their back and actually be able to get anywhere. I think some people rule out walking all together, because they do not consider it an option. Don't plan for an escape route that you and your family are not capable of utilizing. Don't plan on carrying what would be too heavy. If you have different plans or levels of plans, plan for differnet kits. For example, if a car might be an option for you, plan on stuff you can take using the car, but also have a plan if the car cannot be used or in case you must abandon the car. Always have a plan for bugging in too, because sitting in your home with your supplies may be the best option.

Finally, if you continue to do this, you will realize there will never be enough. You will never know if you preparations are enough until the peril is over.

One thing you can never have enough of is knowledge, but your supplies and kits may constantly be reanalyzed and rearranged, and thought about over and over again. That's not a bad thing, because thinking about it simply means you are continuing to prepare and that your preparations continue to improve.
