As an avid fan of zombie apocalypse movies and comics, I should throw in my two cents.

Find yourself a Super Wal-Mart or similar department store. Firearms, ammo, mattresses, canned food, bottled water, TVs, internet, and anything else you need to hold off on the year long siege. Wal-Marts have glass entrances, but can be protected by their metal cages that descend from the ceiling. Bring with you family, friends, and other survivors to barricade and clear the store.
Once you secure the store, send out convoys to the local National Guard armories for weapons, and find specialists who can operate nearby powerplants and water treatment facilities. Hopefully you wont need to do this, but every little bit helps.
