If you have phone books and duct tape use them. Wrap your forearms and your biceps and tape the hell out of them.The same goes for your shoulders and the back of your neck. You have to get creative but cover some of the most obvious places you would get bitten. This would be usefull if you had to go out in search of supplies. If you have some leather material or old coats you can combine with the phone books to make a more practical armor that you could throw on opossed to having to re-tape everytime. The idea is protection but don't make something you cannot run well in. You never know when you will encounter a runner or even worse a fucking pack of them! I have actually combined this idea with our standard gear where it would improve our own armor. When supplies are limited you use what you have.
