Weapons:
A crowbar, though I do know a few places to break into for shotguns and rifles if the Zombie hordes begin to mass up...
Hideout:
A cabin in the middle of woods. Plenty of fish, berries, game and other sources of food nearby. No trace of civilization for 30 miles. During winter I could get there with a snowmobile/skiing, during the summer with a bicycle/a car. No, I don't own a car. Yes, I can hotwire some models.
Companions(if aplicable): A few mates of mine, though only if they were not a part of the zombie horde.
where you'll go: To the middle of nowhere.
supplies: A few medkits(accidents do happen while moving in a hurry), batteries, radio, a generator if possible, some tools for building/repairing stuff. A practical knife, a compass and maps (these are a must), ammo, though it would be a problem to gain in any large quantities. Food and water only enough to last the trip, nature would provide the rest once at the hideout.
But really, all you can hope for is that the zombies are distracted enough by eating the other people while you gather the supplies and your mates and get the hell out of dodge.
Pros of my plan: Not complicated, discounting the zombies extremely easy to execute. Almost all the required supplies are within 5 minute reach from me, at any given time. The hideout can support us as long as there is any food in the nearby forests/lakes. Hideout could easily act as a base for raiding missions into towns, assuming you'd got some kind of motorvehicle. Plan can easily be adapted to any number of people less than a dozen or so, including the assumption that only I manage to escape to my hideout. Works best during winter: Snow and icy lakes slow down the zombies, while giving me an huge speed-advantage with skis. The only truly critical equipment are only the knife and a map and some kind of water container, even if small. Even a compass can be done without if truly necessary, though it would significantly increase my chances.
Cons: Any prolonged battle with even a small group of zombies likely results in becoming dinner. Getting guns would be a problem. If whatever caused the zombification spread via water/air, the plan would not work. The plan hinges on speed of execution and ability to quickly exit any populated areas into wilderness where the feet-dragging zombie hordes would have no change of cathing up with me, even if I were on foot.
