Yup. I've got...
15 gallons of water (I probably need more than this. It's on my to-do list.)
Tons of food (again, I probably need more)
Batteries...and more batteries
Matches and cigarette lighters
Pliers, hammer, and other tools
First aid kit
Sweatshirts, jeans, beanies, extra socks and other warm stuff
Extra pair of prescription glasses (for when the contacts finally fail)
A harness and leash for the critter (because, c'mon...in the event of the apocalypse, I'm not going to keep my cat in her carrier indefinitely)
Lots of toilet paper (my @$$ deserves the best, baby)
I have a little, portable camping BBQ
Self defense...both in the kit, in my truck, and all over the house, really. I've got an axe, three geology hammers, a tomahawk, a crowbar, a bolo blade (it's like a machete, but better), two hatchets, a baseball bat, pepper spray, and tons of knives.
I've got a few other odds and ends in there, but this is the gist of it.
