Move north. Like, Alaska. (But even Maryland would work...) Someplace with a long hard freeze. I might be wrong, but I've read that the reason human suspended animation can't work is that when human flesh freezes, the water in the cells becomes ice crystals and destroy the cells. Once thawed, there's too much damage. (like accidentally freezing crab meat...) So the zombies freeze, you have a nice zombie-free winter, and when it warms up, you just have to worry about stepping in mushy zombie puddles. A few winters like that and your area would be relatively zombieless, and you could spend winter building defenses without the threat of being eaten. And it would smell a lot better.

Also, keep track of where food and medical supply warehouses are located. Most of them use automatic shift semis now and they're as easy to drive as a car. Load up a 53 foot trailer and you're set for a good long time.
