Here's a fun video on "How to Zombie Proof Your Car" from an Australian car show called Mighty Car Mods. http://www.youtube.com/watch?v=iS8KXHBCimo
The idea is to modify your vehicle so that it can protect you against zombie attacks using materials you might have available around the house. It also covers gathering supplies, weapons and tactics. The video is fun, irreverant and informative. Saul would have benefitted from seeing it before he took charge of the motorpool!
