For the guys that are saying flamethrowers and chainsaws...
how do you plan on carrying the fuel for it?
Carrying gasoline can be very dangerous. I'm not familiar with how flamethrowers work, but what if a zombie came up from behind? And not to mention, the ensuing flame wall that you create could box yourself into what ever area you're in at that particular moment. Not only would you have problems finding a flamethrower, but you must consider the dangers of carrying such a weapon. The zombie that your spray will not die immediately, so you'll be surrounded by a bunch of flaming zombies.
As for chainsaws, the fuel makes it a problem, unless they are coming out with hybrid models. And the safety concerns make it a weapon of last resort.
As for bringing Arnold, as I said, humans tire eventually. And I'm willing to bet Arnold will be in a bunker somewhere. Good luck getting to him.
