As long as they aren't evil magic zombies, I think the zombie threat is overrated.

As magic keeps those muscles moving, dehydration, infections, rigor mortis, and decaying flesh don't really matter. After all, the whole point of magic is to violate the laws of physics and chemistry. With the other types though, decaying flesh does matter, which means that the problem will solve itself within a few days. Just keep the doors locked and windows closed in the meanwhile.

If you happen to be outdoors camping when the outbreak occurs, you don't really have any doors and windows to keep you protected. If you have enough food to keep on camping for a few more days, you might be fine. After all, zombies are in the city, where there are lots of people. You're out in the woods, so you might miss the whole zombie apocalypse when you come back home a week later.
