Obviously they have never taken the Bay Area Rapid Train (BART). When the first train hits the first stop, all the bums that slep on the train over night smell like hell, the entire section of the train they are in smells like a zombie would - like death. Nasty as heck. Those are zombies, they can't even be woken up, they just shit and piss all over themselves and pass out on the seats. Even cops don't want to touch them.
