I have a mini emergency bag in my car since I travel. It contains some food items, collapsable water bottle, some various pills, foil mylar blanket, CO2 pellet pistol (I'm in MD, can't carry a pistol, but working on a "solution"), knife or two, some first aid stuff. And I have an army blanket, flashlights, and fireextinguisher in the car trunk.
Bug out bag in progress. Weapons- Keltec SU16CA, M57 Tokarev 7.62/9mm, food bars, water, medicines, matches, knives,two way radios in mylars, small books for the kids, LED flashlights that can regenerate power by crank or lever, plastic bags, mini binoculars, compass, Boy Scout book, and other stuff I can't remember right now.
And a kitchen sink.
