People who carefully and painstakingly prepare for mass extinction don't exactly seem like the type of people who plan great parties. At least, with those vast collections of guns, ammo, and other terrifying armaments, I certainly hope not. Then again, I suppose everyone will need a drink or 10 to get through the inevitable horrors of forever navigating the "what's for dinner" question without Seamless or, you know, realizing that your urban-dwelling family members will probably never arise from the blasted pit of rubble where their apartments once stood.
I.N.C.H. pack: I'm Never Coming Home pack. (It is another name for a Bug Out Bag. often used by those trying to show that they are experts in the preparedness field.) A pack containing everything needed to walk out into the woods and never return to society. It is a heavy pack loaded with the gear needed to accomplish any wilderness task, from building shelter to gaining food, designed to allow someone to survive indefinitely in the woods. This requires skills as well as proper selection of equipment, as one can only carry so much. For example, instead of carrying food, one carries seeds, steel traps, a longbow, reel spinners and other fishing gear.
Common preparations include the creation of a clandestine or defensible retreat, haven, or bug out location (BOL) in addition to the stockpiling of non-perishable food, water, water-purification equipment, clothing, seed, firewood, defensive or hunting weapons, ammunition, agricultural equipment, and medical supplies. Some survivalists do not make such extensive preparations, and simply incorporate a "Be Prepared" outlook into their everyday life.
Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
