I wondered about how so many walkers are not just bones by now but then remembered that ALL are infected. So those that survived, then die of a heart attack or something..they turn into walkers. So it is a none stop "feeding" of the virus on all living humans. Which makes me wonder..are there zombie dogs? Cats? And what about walkers in the ocean or in lakes that fell off boats and drowned. They rot and just keep wandering the depths until their skin and organs rot while feeding on fish? I wondered about that when they fell in that basement and that water logged rotten walker got tyrese. Shouldn't they have been rotted to nothing by then? Kinda hard to bite when there are no jaw muscles.And again. How is it these guys can go to the top of a mountain in a hurricane and every walker in the tri state area heads to that spot? That shit is old.
