It took me 3 afternoons, but I actually read through the last 18 pages of this thread and I found some great ideas.
As I stated in my intro thread, I'm a SAHM of almost 4 kids (due in August) and the last thing I want to do is to "bug out" to the Rocky Mountains with only supplies on my back. The kids hate half of my home-cooked meals.. why would I want to listen to them complain about dehydrated backpacking food AND being cold AND sleeping under a tarp AND...

I digress. I have a backpack GHB/Mini Emergency Rescue Bag stored in my car to get us home, where we could meet up with my husband and decide to hunker down or go. Plus, 90% of the time I'm within 15 minutes drive of my home, and the rare exceptions are trips to the zoo - maybe 35 miles away? Other then that, I'm either home or we are out together as a family anyway.
I live in the Mountain West, and aside from the more common small threats to our home or immediate area (I do live very close to a freeway, so overturned trucks could pose an issue), is an earthquake. I've done some research and if it is the size they predict, roadways will be completely unusable except for off roading. I'm not even sure if I could use a jogging stroller, but it might be my best bet. It is proposed that several dams will break when our "big one" hits and the valley will flood. But I live in an interesting spot - fairly close to a freeway that is much lower than me. I'm assuming the water will fill that portion of the freeway and our home will stay dry. (Would I be able to count that as a good source of treatable water??)
Here's what I've got in my car bag now. I've been grateful for it on numerous occasions when the kids needed a change of clothing because of a potty accident, or we were caught in a sudden rainstorm and I pulled out the ponchos, etc. But any tips are greatly appreciated because realistically, I have no idea how I would carry this heavy bag AND encourage/carry/drag the kids home as well. Not to mention carry the baby when he gets here. I imagine a walk home from the zoo would take our group a few days! (Haha..)
NUTRITION
Foldable plate, bowl and cup (similar to this
http://www.backcountrygear.com/fozzils-solo-pack.html?gclid=Cj0KEQjw2fLGBRDopP-vg7PLgvsBEiQAUOnIXJ-QYIqJzrbQtfK_vNiVPvCScY5cjDGUhmc9iviuPK8aAuUO8P8HAQ. I love using the plate as a cutting board when we go on picnics at the park, and I figure it will be useful for dividing/prepping the snacks on one of our many rest stops)
Utensils (light my fire minis for everyone)
GI can opener (Honestly don't know why I included this. I don't have any canned goods packed, but maybe we could find some?)
3 SOS Food Bars (3600)
3 Millenium food bars
3 quart ziplocks with 12-14 snacks each (pb crackers, tuna pouches & ritz, raisins, trail mix packets, granola bars, stretch island fruit leathers, gum, apple sauce pouches, kool aid mini mix packets, etc)
Sawyer mini water filter
2 oz container/dropper with bleach
27 oz single wall, stainless steel water bottle (to store water, or put close to fire and boil water if absolutely needed).
CLOTHING/SHELTER
sweatshirt and sweat pants for each child and myself
1 change of underwear per person
2 pairs of wool socks for me, 1 for each kid
warm hat/person
gloves/person
rain poncho/per person
2 mylar sleeping bags
3 mylar blankets
10-12 hand warmers
2 emergency tube tents (the bright orange ones

)
FIRST AID KIT -
https://www.rei.com/product/784495/adventure-medical-kits-womens-outdoor-first-aid-kitI also stuffed in the following:
mini vicks vaporub tin
more tylenol 500s
children's liquid tylenol
children's benedryl
nuskin
teething tablets
forehead thermometer
extra kid-character bandaids
biofreeze pouches
1 instant ice pack
aquaphor (diaper rash, chapstick, etc.)
duct tape around a credit card (to prevent blisters + a billion other things)
HYGEINE BAG
washcloth
wet ones
shampoo/conditioner
johnsons/johnsons head to toe tear free soap
hand sanitizer
chapstick
deodorant
toothpaste
tooth brush
cotton swabs
travel comb/brush combo
kleenex
small finger nail clippers
compact mirror
sunscreen
feminine products
(Although I love having many of these things in the car for day-to-day things that come up, I'm thinking I will keep them in the front of the car and have a smaller bag in the emergency kit with just the basics - all purpose soap, sunscreen, feminine hygiene, and hand sanitizer)
TOOLS/SUPPLIES
toilet paper
handy saks (plastic bags)
flint and steel (ha, told my husband that I need to actually start a fire with it this summer)
2 bic lighters
whistle / compass /waterproof match container with matches
ziplock of fire starters (made by dipping/coating cotton make up remover rounds into my Sentsy Candle Warmer after the scent has worn off. Waterproof until you rip them a little to expose the cotton fibers before lighting. They burn for like 5 minutes!)
a very small flashlight for each kid (entertainment? comfort?)
2 headlamps with extra batteries
permanent marker
$100 cash - small bills, plus whatever change is in the car..
multi tool from emergency essentials
little bigger single folding knife
ENTERTAINMENT/COMFORT
tiny scriptures
sudoku
tiny bubble container (from a wedding send-off)
Yahtzee assembled into the little white containers that travel first aid kits come in
chalk
pen & small notebook
a travel game that we got as part of a kids' meal
3 hotwheel cars
mini 4"x4" versions of my kids' blankets for the younger ones
I also keep a case of mini water bottles in the car, and a basic camelbak for each of us so we could fill them up and the kids can at least carry their own water. The downside is they will probably drink it faster than they should just because of easy access.
Plus, after August I'll need to add in diapers, wipes, and a few other baby related items. Also thinking about purchasing an emergency childbirth kit just in case. (I deliver at home with a midwife, so at least I have better-than-most experience in that area as long as there are no complications).
No idea what to do about protection/defense. And I'm probably a target with a bunch of kids and a big backpack of supplies, aren't I?
Nor communication. I do have a couple 2 way walkie-talkies, but I think they have a 2 mile range. Not really helpful to get ahold of my husband if I'm further than that.
Thoughts? What am I missing? What can I ditch?? TIA
