I agree with you, TRO. I'm moving towards the same modifications, with these additions:
1)I'm looking into an inexpensive storage building (actually, 1/2 unit) on my most-probable evacuation route. There I'll probably keep supplemental (even duplicate) supplies.
2)I bought the Eton-Grundig 300 radio, which can also charge cell phones.
3)I already use an on-line data backup service which automatically uploads designated files to two remote storage servers (East coast and West coast). I've scanned into a folder (and this gets stored here, and remotely) the following:
a)digital photographs, in some detail, of my home and office structure and contents.
b)important documents such as insurance records, car titles, home title, our wills, and advance medical directives.
c)an abreviated medical records file.

I have contact persons in a remote location who can access this online storage if necessary.
