I'm glad I found this question before they found you, definitely not.
You couldn't even fight Dick Cheney with a crowbar. You want a weapon that will keep you further from the enemy or has much more power if you are going to be outnumbered. A katana or a spear would be preferable, but even still that's a little close for comfort. A blunt weapon like a crowbar would only allow you to knock a few zombies down at best, but they'd pile up around you and you'd be quickly outnumbered.
Let me reflect on this question...
Homemade explosives and booby traps are where it is at my friend. You could make 10 gallons of napalm for about $20, so I'm sure you could heavily fortify the rear of the house using any and all furniture possible. Block all doors and windows completely, do this to the front windows as well but leave the front door alone. Every good fort needs a weakness to funnel in the enemies, and when they come you'll be able to throw everything at them. The bodies will stack so quickly that they will be severely slowed, and don't use more napalm than necessary cause it leaves a smell.
No joke, there is an ad on the side of my page that said:
"My Weight Loss Success Based On The Diet I learned From Rob Zombie.
Rob Zombie Keeps Weight Off Using This System."
So I assumed it was a joke of some sort... it wasn't, but what's a T-virus? Will it really help me lose weight?
