My GHB/BOB is always in my truck, and that is always near me, so guess it's EDC. On my actual person, I always carry a Leatherman tool, which generally has what I need. I have a credit-card sized tool in my wallet, and a couple of small items on my keychain that are handy (including a small LED light).
In the GHB/BOB though, pretty much have my pistol, food, water, tools, first aid, and all kinds of other doo-dads. In addition to that though, there are other things in the truck such as a change of clothes (into more wilderness-friendly clothes), hiking boots, machete, more tools, and other vehicle needs (like spare fluids, siphon kit, entry kit, etc., etc.)
I could go from software worker to Rambo wannabe pretty quickly, hehe...even though I'd just look like a dorky wilderness hiker.... Of course, my real goal in getting home would be to NOT be seen by anyone, if I could help it, anyhow.
