This is the “Oh sh*t!” lunchbox…the lightest weight “grab this and run” case that I have set up. (Other kits are available in each car, and there are individual bug-out bags for family members, but those weigh in at about 45-60 lb each.) This one weighs less than my purse.
BTW - I’m not really much of a conspiracy theorist, but if you live in a place that gets periodically whacked with killer floods and hurricanes, you get into the habit of being prepared for anything, and I was really bored a few years back. This was just for fun.

The kits are kind of an on-going project for me, and I haven’t updated them since getting into the essential oils, so I’d probably modify a lot of the stuff in these with the oils. They’re a lot more effective than OTC drugs in a lot of cases.
But I love seeing what other people have done, so keep on posting pics!
