"Rage" Infected don't count when using the standard term "zombie".
Zombies are the undead. And the dead suffer from an affliction called Rigor-Mortis (sp?). Hence, the shambling motions.
So, "zombies", in fact, cannot run. This is, of course, according to George Romero. Since he would know.
Anything else is unnatural.
Anywho, here's my survival sheet...
Ragers aren't even dead, let alone un-dead.
Rigor mortis, however, dissipates after a maximum of 72 hours. There have been numerous zombies not only running, but some even jumping! (Mostly shambling, though).
I could never get into all that Hollywood zombie crap... not too fussed with all that recent vampire crap, either.
Nah, if I want horror, I just turn on the 6 o'clock news.
The recent vampire crap has nothing to do with vampire crap in general! It's just crap!
The horrors of the 6 o'clock news isn't the fun kind of horror, though. Just the suck kind.
