one of the earliest signs of my chronic paranoia was the fact i kept a bug out bag (bob) ready at all times. sleeping bag, knives and whetstone, 30m of paracord, firestarter, and clothing. i never went anywhere without it. by the end, it had grown to include freeze-dried food, water purification tablets, a hammock, a compass, a medkit, an antitoxin kit, a couple of survival books to read the stars and forage, and a recurve bow with fifteen arrows.
i'd grown dependant on it, and it inspired my friends to have a camping checklist to bolster my bob (that could barely acommodate two people snugly).
i'd disappeared off the face of the earth twice before getting help. now, it's more kitted out for winter camping (which i love to do), but it could come in handy in case of impending doom regardless of circumstances. it's still pretty much intact to what it was at my most paranoid, but i tend to leave the bow behind unless we're planning on spending a weekend target-shooting.
even though i can only can count the "lost time" i experienced, it seems i could bug out and disappear in under 20 minutes. a three hour round trip took me 150km out, according to my car's readings.
