Zombies?......Id be more worried about all the people pointing and laughing at my "zombie proof car" and suspecting I was twelve years old and play too many video games than any zombies. They don't and nor will they ever exist.....well, except the ones in yours and our governments I guess! Why not equip your Jeep for something that might happen.....going off road, floods, rock crawling, hurricanes.....anything other than bloody zombies is fine with me!
Before you judge a man, walk a mile in his shoes; after that, who cares?! He's a mile away and you've got his shoes!
