Very good advice. You've given me a lot to think about Eugene. I thank you for that. We have the the BOBs for us built into the so called pilot bags. They currently reside in a closet in the bedroom, along with a backpack for the baby.
You mentioned pets. Her ferret and both cats sleep with us so the ferret can be taken, though the cats mite just get in the way while we get out then run away. The dog sleeps besides the babies bed. We call her the baby even though she's two.. Since you've mentioned fire I now consider if I can destroy the wall to get to her in the next room if the hallway is on fire. We have French doors leading to a patio off the master, so us getting out should be no problem. But there is the issue of getting her out. All photos,documents etc are duped onto a flashdrive taped inside my locker at work and updated monthly. Papers, drives etc are in a five star binder with a shoulder strap sewn onto it and kept on the bedroom desk. We'll be moving our keys and cells into the bedroom starting tonight, and there are two way radios in the BOBs. I doubt a shelter would accept the pets but the ferret is quiet and I would give them no choice with the dog. Saddlebags for the dog seem a good idea, and he's absolute security for my wife and the baby.

Ideally we could simply get in one or possibly both SUVs and drive away, perhaps with the small trailer attached, or go to a smaller home we own and are currently finishing up renovations on.
But when it hits the fan such niceities are rarely actualized. We can sleep in an SUV if need be, and a more realistic scenario would be bumper to bumper traffic held up by broke down vehicles and when we do arrive in a safe location no rooms would be available ad we might be forced to stay in a shelter, which are security nightmares.
So, if reduced to the one bag thought, I'll have to carry a lot of everything.
Though three days seems to be the rule of thumb before help arrives I would prefer a week, i keep remembering Katrina and how they waited. And waited. We can do with less food but the baby eats like a horse, so does the dog. Water is a concern, and medical.
I see a lot of work going into this project. Thanks once more for your insight.
