Zombies are magical. If you can accept them walking around you should be able to swallow that they never quite finish decaying.
What bothers me is that the survivors don’t wear body armor. A leather jacket, even, would cut the odds of you being eaten considerably. And that’s the main threat from, zombies, isn’t it: that they’re biters. They can poison food and water supplies, I guess, or cause structures to fall on your head, and generally get in the way. But the eating is the main thing.
Honestly, any half-way intelligent person would have no real difficulty surviving to old age in that environment. There would be plenty of food, ammo, water, and medicine left. Building defensible structures (against zombies) would be trivial — even if you don’t have the knowledge yourself, a few days in a public library would tell you all you need to know. Add to that simple tools of deception (remote controlled cars, radios positioned to attract herds, etc.), and the only thing you would have to really worry about is other living people. But, once again, a relatively secluded spot would do the trick.
I think the odds of survival would be much greater there, than it would be in the wrong area of most US cities.
yeah they should have been scrounging up all the armor off the dead guards in the prison. way stupid to not write that in. that’s natural preservation instinct, they blew it.
