Once the zombie apocalypse comes, tried and true methods of subterfuge like camouflage and misdirection probably won't work. Recognizing this, the gang on The Walking Dead comes up with a way to blend in with their new zombie neighbors.
The best route to a truck filled with tools needed for escaping Atlanta leads Rick and Glen right through the zombie masses. Picking up on what triggers the undead hordes, the group guesses that smelling like a zombie will probably keep the real zombies from trying to eat you. But how does one get that fresh zombie smell?
Look at your man. Now back at the zombies. Now back at your man. Now back at the zombies. Thankfully, your man is not a zombie but he can smell like one.
Now, they are free to wander the streets as they please. Unless, it rains.
You know what they say about the weather during the zombie apocalypse. If you don't like the weather, don't wait five minutes because there are zombies around and you have bigger problems than the weather.
