I read through the main groups stuff and they had references to folks knowing about zombie apocralypses in there so I threw it in.<br/><br/>If the general consensus is to change that then I can...<br/><br/>I don't believe it would take too long for folks to realize that hitting the things in the head is the best way of stopping them, and for that info to have spread via TV and radio over the first few days. Though by that point it would very likely have gone way too far to stop.
