A situation like this brings movies like 28 Days Later to mind... Even though the infected in that movie weren't technically "zombies" the genre is considered to be zombie-horror. Therefore, there isn't much of an idea as to what you could consider a zombie other than what we've made up. If anything like a zombie were to exist, I'd think it would be something like the infected from 28 Days Later.
If a zombie apocalypse were to happen though? I would stay home where I know I have food, clean water, and a sufficient amount of protection. Take a walk into my garage and you'll find a year's worth of frozen deer meat, an enormous pack of bottled water, fresh vegetables, and ice cream. :) You'd also find the two 20-Gauge shotguns, two 12-Gauge shotguns, 9mm Ruger classic series pistol, black powder muzzleloader, and enough ammo to keep you armed and loaded for about one to two months, not to mention the chainsaw, sledgehammer, spade, and other potentially useful gardening tools. I have the ability to handle most any firearm well enough to hit a target and I can still MacGyver quite a few things to use in a practical situation, not to mention that if I needed food or water, I could simply walk down to the Wal-Mart about a mile away and bring it back. If I run out of ammo, I can still go back to the same Wal-Mart and take a bow with all the arrows and arrowheads I'll ever need. I think I'm set.
