Allright, my plan is simple. For the sake of argument I'm presuming we have a condition only transmitted by bites of the undead, and that we're dealing with slow not particularly bright zombies.
I live in the country, have a 5 acre property on a small river, thoroughly protected by fencing along the road, and blackberries elsewhere (even a zombie ain't getting through a mile thick blackberry patch). I keep about two weeks worth of food and water handy, and could probably live a long time on fish from the river and game. But that ain't my plan.
