I have a car kit that is very extensive, but I also have a small carry kit. My small carry kit has a few essentials: 1 trash bag, small pocketknife, magnesium bar w/ striker, 12"x15" aluminum foil, 25ft of paracord, 25ft high strength fishing line, 2 or 3 safety pins. It's not much, but it all fits in a small leather pouch I have and can be easily carried in a pocket or hung from my belt. The items are fairly self explanatory and are really used as a last resort (like if I got separated from my car). In addition, in my pockets I also carry: chapstick, a lighter, a extra pistol magazine, a flashlight, wallet (which can be used to hold several cool items such as razor blades, paper for tinder, and bobby pins), a clip on pocket knife, and as always: a pistol. At any given time there may be other items present that could be useful in certain situations. I figure this combination of "stuff" would be sufficient if I had to "bug out". Of course I'd try to get to my car first, but we aren't talking about car bags...
