Just climb on top of your roof, with a rifle and lots of ammo. Bring a radio, MRE's and a couple gallons of water. You might want a shotgun, in case one gets smart and figures out how to climb up.
Shotguns are the ideal zombie dispatching weapon. I would even grab a sword or machete in case you run out of ammo. Of course, you want to bring a single hand grenade, so if you get bit, you can go out like Will Smith in 'I Am Legend.' :biggrin:
