On a happier note...

I really like the concentric rings idea. I will make use of that.

As far as bug-out scenarios go...remember that if things go really, really bad, you ought to have a plan for long term survival. This means a place to bug out TO, and a plan for what to do when you get there. For me this means a place with some acreage out in the country, a group of (armed, trained) people to make sure the place stays secure, and the resources and skills to stay there long-term.

This would be your "outermost" ring.

For me the most useful thing, since its useful in general bad times that last even only a few hours/days, is an emergency bag.

My emergency bag stays with me wherever I go. It has extra ammo for my CCW, clothing, first aid, food and a compact longarm along with ammo for it. It also has maps, a compass and routes of evacuation marked on them. These are maps for either vehicle or foot that allow me to avoid major freeways as much as possible (vehicle) or stay away from likely danger zones (foot) going to my home, or to several places that will (probably) be safe in the event of the worst, along with a last-ditch foot route to the designated bug-out house. The wife is similarly equipped, minus the longarm.

Due to obvious problems with having ammo and weapons in a bag, as I said, it goes with me wherever I go. Its locked in the truck only if I'm going inside for a quick shopping trip. If I'm staying for a period (work or at a friend's house for the superbowl, for example,) it goes with me. I am fortunate that I have good friends who appreciate my hobbies and interests rather than just think I'm crazy. The main purpose of the bag is to enable me to get out of any short-term disaster (riots, freak blizzard, whatever) and back to my place or, last-ditch, make a non-suicide run for my safe place.
