Agree 100%. In fact, every American should do so, because a pandemic or a really bad terror attack could leave us all on our own for days, maybe weeks. Iagine if they managed to nuke four or five major cities on one day, for instance.
When first discussion of the SuperFlu (H5N1) came up, my family reviewed resources and decided at what stage the grandkids come live in the country with me, and at what stage their parents join us.
You're very wise.
Well, this is America, land of the self reliant... :D
