We always try to have at least 3 months supply of canned and dried foods, ever since a tough financial spell the first decade I was married. Not having to buy groceries saved us then, so even though money hasn't been tight since, we still have the groceries and rotate stocks carefully so that what we store is really what we use on a regular basis.
We have a good hand pump water purifier, because while I still was able to go, we did whitewater rafting.
We just took out half our back lawn so that we have a garden spot. Before this year all we had was a little exterior grow box. But the more I read about nutrition, the more I'm finding out that now they breed produce to travel well and that has the unintential result of breeding nutrition out.
Most new varieties of produce have measurably less vitamin content than heirloom varieties, for example. So since my body needs all the help it can get, we're going to grow our own, hopefully more nutritious, foods.
Regarding guns and ammo, my spouse is ex-law enforcement and he worked undercover for a lot of that time, so the gun safe is always stocked and has been for decades. That's also why we've always had a bug-out bag packed and ready.
And don't forget to rotate the medications in your BOB!
Regarding communications, we have a ham license and some high powered walkie-talkies. And a close relative (living close by and closely-related, both) is a big cog in the federal emergency response machine, so I'm hoping that covers that one.
We won't think about Katrina.
So that's my preparedness report. FWIW.
