G.O.O.D Bag/ 72 hour kit

I made my first 72 hour kit several years ago. I used a plastic tote box (the kind you get at Wal-Mart) and it served its purpose. It was able to hold everything that I wanted. It did have drawbacks though; it would be very difficult to carry it any long distance and it was not very durable.

I have decided to re-do my kits now that my kids are getting old enough to carry their own stuff (at least most of it).

I've been checking around and reading up on what I need to have in my kit. There are several commercial kits like this one:

This kit gives a complete inventory list:

1 - Backpack 1 - 3600 Calorie Mayday Food Bar 1 - Vegetable Lasagna 6 - Pouches of Water 1 - Mayday large Solar Blanket 1 - pair of Work Gloves 1 - Adult Poncho 2 - 12 hour Light sticks 1 - Dynamo FM Radio w/LED Flashlight 2 - Maxi-pads 1 - Clear Solution Hygiene Kit 2 - Pocket Tissue 2 - Wet Naps (3 pack) 1 - Yellow Rope 1 - Spoon/Fork Combo 1 - Blood stopper Trauma Dressing 1 - box of 50 Waterproof Matches 1 - Slow Burn Emergency Candles 1 - Wag Bag Sanitation Kit 2 - Anti-Bacterial Bar Soap 1 - Blue Tarp 1 - Personal Water Filter

I think this would be a good start- I also plan to include:

A change of clothes (2 changes if room)

Extra boots

Small Bible

6 MREs

Hatchet

Knife

Cash and change

Maps

Collapsable shovel

All of these are easy to carry and easily obtained.

What other items am I overlooking?
