On me when I'm out and about in the Houston area:
1. Doug Ritter keychain flashlight thing.
2. MiniBic lighter
3. REI miniwhistle (works great at homeschooling events to keep the kids in line)
4. Leatherman Squirt
5. Kel Tec PF-9 + spare magazine
6. County Comm peanut lighter
7. P-38 can opener
8. Cell phone (non-smart)
9. White hanky
10. Weather-appropriate clothing
11. Cash and credit cards

When I'm at work I have to leave the PF-9 at home but everything else is on me any time I step out the door.

Over the years I've cut way back on what I carry on my person. However, both our vehicles are ready for the apocalypse.
