My bailout bag (actually a cop equipment bag) with the main ingredients:
The big challenge is to fill it with the little stuff that's still needed in a crisis. I have spare glasses (I'm dependent on glasses), a week's worth of prescription meds, and a first aid kit with stuff like lip balm and sun screen. Plus other little things like a boonie hat, wool watch cap, gloves, a little bit of food and water. I've also got three sources of fire, and three sources of light (should throw in some cyclalumes, too).
About once a year, I take everything out, and think long and hard about whether it should go back in the bag.
