So, the link was busted a LONG time ago, so here we go with the Google Cache version from around noon. Even this link will take a while to load. You can probably thank Fark.com for both getting me the Cache link, AND for crashing the site.(I'm sorry, but they're Alexia ranking is over 1000 lower than escapist, which surprised me that Escapist's is actually in the top 3,500)

So, anyway. The concept of survival in a zombie apocalypse isn't too different, unless the infection vector is airborne or uses a common insect(flea, mosquito) to infect people. If it's just from bites, then the week's supplies should be fine, two weeks at the most to cover newer infections.
