What is your zombie contingency plan?

I live in a two story house, we have a ton of weapons (swords, guns, etc.) and I would plan on hitting someplace with ammo first, then raiding the nearby grocery stores (have three close by) Roommates have trucks and SUVs and we could barricade the house pretty well. If we board lower story windows and separate the stairs from the house, we kind of have a tall barrier effect. I just wish we could have gotten a wrought iron fence around the front so things were more secure! The landlord had wanted it, but he didn't have the funds when all the construction was finished. The windows on the top floor would be perfect to pick out zombies from. I dunno, better than panicking, eh?
