Well, I suppose in the real world. Doesn't make very interesting viewing though, at least to me. The newer infected zombies are scary in the same way beign chased by a pack of animals, or a linch mob is scary. I'm more old school. I like the slow, half decayed corpses who shamble toward you relentlessly. Sur eyou can dodge or run around them, but theres bound to be thirty more waiting just around the corner.
