My husband (I can't get to watch with me) & my 17 yr old son (avid fan) are always talking about how we would fortify & protect the farm & property if there was a zombie outbreak! LOL
My son is convinced it could happen!
I think that it is very possible...with some super strain of Rabies or something.... I have a gate around my property, and I raise my own veggies and chickens. Now, I didn't know that I was preparing for it, but when it happen I'll know what to do...because of the Walking Dead....LOL
