This looks like fun!

My $0.02 worth.

A list of contacts: names, addresses, phone numbers.
Copies of important documents in waterproof containers.
Ready cash
A red LED light incase you have to travel through a hostile area at night.

Everyone in our family has a CamelBack. Each CamelBack has a PSK. You know the list: fire, First-aid, Food, Navigation, shelter, signal, water, and knife/tools.

Your family BOB seems to be heavy on candles and light on water. In a natural disaster or terrorist attack I don’t think you can assume the water will be good. You have 2 Nalgene bottles and 4 zip-lock bags. You might be better off using Katadyne Microupur MP1 Tablets. I have tried them and the water tastes normal. Children hate weird tastes. I have 4 boys, I know. MP1 also kills viruses. You might want one of the folding 1 gallon water bags.

If you have plenty of water make sure everyone has lots of snacks.

I am not happy with your light selection. We use LED headlamps. They are a great hands-free light for when you are working at night around camp. A SureFire G2 can’t be beat for when you need to see what is out there.

Make sure your kids have a whistle all the time.

Keep a Glock 23 or 27 on you at all times.
