We had floods where we lived in Mississippi, so we learned some tricks – we keep a bag with clothes for everyone, a checkbook and a spare ATM card and basic toiletries and some towels where we can throw it into the car at a moment’s notice. Of course, if we can’t get to our car, it becomes moot, but it certainly helps.
Anyway, to the OP, I’m working from a presumption that I’ll have five to ten minutes, in an evacuation order situation, so I could successfully grab stuff and walk out to my car and then drive away. This is what I’d get, it’s listed by priority, so if I don’t get to the bottom of the list, I’d be hurt but I’d live:
The lockbox containing our important documents (birth certificates, passports, wills, etc.)
The Matisse that hangs in our living room
The 2 baby books and 1 main family photo album
The childrens’ favorite loveys, my teddy bear and Mr. TeaElle’s rag lamb
The CPU of our file server
A laptop so that we could get online sooner rather than later to communicate with people
My jewelry box
The DVDs of our wedding, Baby TeaElle and other stuff
If we had to get out with just what we could quickly put our hands on, like in the middle of the night, it’d just be the lockbox, the Matisse if at all possible, and maybe the laptop because it’s always fairly convenient.
The fires have reminded me that it’d be a good idea to get all of our irreplacable family photos and some of our documents backed up onto a DVD that could go into the lockbox or our safety deposit box. I also want to look into the usefulness of those safes that are supposed to withstand the heat of most house fires. I don’t think that they’d save us from an inferno like California, but thankfully it’d be very hard to have something like that here.
