The Walking Dead

I have been watching the new TV show The Walking Dead. It is pretty much a zombie movie made for TV, based on a comic book of the same name, but it is good. Interesting characters and adventures.

The group hiding out in the woods confounds me a little. They are worried about zombies showing up but have built NO defenses. Even a rudimentary palisade would at least give them time to get in vehicles or get ready to fight back.
