Oh noez, LC is onto me.
Okay, I'll play along and give a more serious, detailed answer, since CL inspired me.
Preparations and Supplies:
No one is fully prepared for a zombie apocalypse unless you're Burt Gummer, and he's fictional. I'd marshal what non-perishable supplies I have on hand (which is usually a lot), such as canned food, dry goods, basic medicines (fever reducers/painkillers, generic antibiotics like penicillin and amoxicillin that work on a variety of pathogens) and first aid kit (bandages, antiseptic/hydrogen peroxide) as well as water purification tablets. My roadside repair kit also has some goodies I'd bring along (flares--very useful distraction, or attention getter should by some miracle the cavalry arrive--tire iron, basic tools). I have access also to a Remington 700 chambered for .308 Winchester. Normally I only keep on hand high-accuracy 'match grade' ammunition, but that stuff is just for being super accurate and not always readily available. First stop would be to get as much cut-rate, readily-available ammunition possible. The important thing to remember would be that for any gun on hand (Say, the trusty .45 Caliber ACP Operator), ammo will ALWAYS be limited. So I can't weigh myself down with two much of it, and there's a limit to how many magazines I can have on hand even with an ALICE or MOLLE webbing vest (about 3-4 single stack mags, and the .308 is bed-loading anyways, 7 shots before needing to manually reload a bolt-action gun. Not terribly useful if you need to mow down zombies in a hurry. This is more of a strategic asset). I keep a sort of 'natural disaster daypack' (First aid, a few gallons of potable water, purification tabs, sterno, matches, candles, some dry nonperishables, hygiene products, map, flashlights, batteries, radio, etc) stored away with most of the small items on hand should there be some sort of occurance. Transferring these items onto a smaller package isn't too difficult. Attach my sleeping bag to the bottom (or top) of the pack, and that's that.
This is an ALICE/MOLLE vest. They're cheap.
You can carry a lot of useful items on them. They can be had for about $50. No reason not to have one, especially if you like camping/hiking. Anyhow, the nice thing is that these distribute your load nicely, and you can always add on more pockets. Magazines, PowerBars, that sort of thing can fit in pockets easily, including my hunting knife and its sheath. I imagine the hunting knife will be less useful as a last resort weapon and more useful as a miniature spade for digging/etc. So, all the little odds and ends I'd need quickly are loaded into an ALICE/MOLLE vest, including a multitool and compass.
A phone wiill only be useful so long as power remains supplied to cell towers, and call volume is likely to make that totally useless from Moment 1. I wouldn't bring it. Anything that can be left behind would be.
The other small incidental I'd pack with me is my audio/video recorder and a notepad/writing implement. Combined with the map from the daypack, these are important materials to put down and record thoughts, locations, and sort information that could become important, as well as to leave behind any useful information for other uninfected human begins should I die.
Prioritizing what to bring or not to bring is very important. The average US Soldier carries a pack that weighs (minus body armor, something I don't have to worry about) 80lbs on average. Even that tires your average fit soldier in a few hours. I can't do that if I'm going to do running, evading the Infected and possibly--almost surely--other humans with less than kind intentions. That 700 weighs like 13-14lbs with its bipod, but it can be hand-carried. Accounting for about 40lbs of supplies (per person, if in a group) is a nice compromise. No room for anything of sentimental value unless it has negligible weight (pendant, etc).
Strategy:
First of all,
I can't take all the emergency water I have with me. Drink as much as I can possibly stand of it without pissing myself. Water is best stored in the body, and I'm in a clutch situation, I won't have time to take a breather and drink up. I'll be running, sweating, etc. So best take what I can with me in the most efficient way possible, by drinking it. This is what F1 drivers do before a race. Check.
Major highways and major state roads are going to be jammed. But, a car is useful in and of itself. My first instinct whether alone or not would be to get my shit, get my car and hit the nearest Walmart, Dick's Sporting Goods, or other place that sells ammo and weapons and get what I can. Depending on when I find out about said apocalypse, that might be slim pickings. I live in a suburban and not major metropolitan area. Chances are, getting out of town immediately wouldn't be the easiest thing. So, after getting what additional supplies I can with the car, I'd head to the nearest Self Storage center I can find. Why do you ask? Well, back when I played in bands, we sometimes practiced in Self Storage units. They're as big as a living room sometimes (some people even store their cars in them!), and generally in isolated locations. So I'd head there, use bolt cutters (I have a set of these in my car, don't ask me why) and break into one and hole up there until the initial chaos dies down. This is an easy source of shelter from eyes and the elements that I don't think most people would think of using. Chances are there won't be any power, but that's fine.
If I have more than two people with me, posting someone to the roof of the storage unit building (preferably with the Remington 700, if they know how to use it, which my close friends do) in shifts will be important. If time allows--i.e., no wandering nearby zombies, or gangs of humans--search the rest of the storage area for anything particularly useful. Depending on the amount of vacant units, it could serve as a nice little base of operations until my group and I are ready to move out.
Getting out of dodge and as far away from the major metropolitan areas a couple hundred miles away are big priorities. Everyone will be jam-packed on Interstate 91, 84, 95, and I-90. Forget those. If we still have access to our car, and still have gasoline, for me getting up into the Berkshire Hills (either driving or walking, heavens forbid) via Route-8 would be the best idea. Largely rural, this area would represent my best route into the deeper mountains north of the Berkshire Hills and into the White Mountains. Getting north and away from New York City (which is about 90 miles southwest of me) is a big thing. That represents millions of fleeing people and possible infected. The Berkshires in MA are sparsely populated and the terrain can be difficult, but offers seclusion. There are LOTS of farmhouses along the way, many of them abandoned (I know this firsthand). There's farmland in this direction, so depending on the season, easy food might be available.
Dealing with The Infected:
- Avoid any contact whatsoever. It's easier for me to change a route, wait it out in a relatively safe location, than to force a head-on confrontation which could cause infection, incidental injury, or use up resources. Time is probably the thing we'll have the most of. Ammunition, water, medical supplies, not so much.
- If avoiding the Infected in any one place is impossible, using a distraction to try and get them to go somewhere else is my first move. How this is done could depend on how the Infected react to stimuli. Heat and light? Flares, or set a fire or something. Sound? Maybe set off someone's car alarm. If they can use their eyes, things get a little more complicated but easier in other ways.
- Even one on one confrontations could be deadly. Dispatching them with the most silent weapon at my disposal (tire iron, baseball bat, a suppressed pistol whatever) is the best way.)
- No matter where we stop, if I'm travelling in a group, someone will have to take a shift as a lookout to make sure there are no Infected encroaching on us.
- Again, avoidance is key. There is absolutely zero need for me or my companions to try and take any Infected on in a fight. There are always going to be more where they came from, and a fight will probably just get the attention of other Infected. Making notes on maps where there are large concentrations of Infected could prove useful.
