If a zombie apocalypse were to happen, I should have a place to stay that is safe, inaccessible to zombies and difficult to reach for other bad-intentioned humans. There's no better place than an island!
Well, if the point is safety from zombies I wouldn't have to worry, after all, a zombie wouldn't sail to an island! So I think this would be a perfect place to shelter from this danger. Humans could even find me, but an island would be easy to set traps on and also to keep an eye on.
The downside of an island is that resources are limited. I would have to be self-sustaining and also use the sea as a source of food. Drinking water would be the biggest problem, and using desalination processes or looking for a larger island where there are fresh water sources would be a solution.
I think an island would be perfect for a zombie apocalypse if I could meet the needs. I could also have a boat to look for resources elsewhere!
