Finally, all those years of being in Boy Scouts can pay off...as a lecturer.
*Ahem* ...I carry a full survival kit in my vehicle at all times. It includes various things needed to survive in hot or cold climates, with the assumption that there will be no prepared food outside of my direct control, in whatever situation I find myself in.
It's got three days ration of water for one person, ready-to-eat food for two days, military-issue MRE's for two weeks, a ridiculous amount of clothing and blankets, a buttload of glowsticks, self-lighting road flares, a flare gun, three or four LED flashlights with extra batteries, a tarp, plastic wrap, 2 rolls of duct tape, about 200ft of rope, a complete first-aid kit, an elongated grill lighter, a NOAA emergency hand-crank radio, two aluminum 4-quart pots, several knives of various lengths and serrations, a collapsible fishing pole, and a mummy bag. The whole thing fits in (and on) a hiking frame-pack, and weighs about 90 lbs.
As far as being prepared at home...not so much. I'm kind of a hypocrite.
