Before the Coronavirus outbreak, I read somewhere that a lot of the super-super-rich have bought land in New Zealand. It's in the middle of nowhere, an island, has a good water supply, has food (sheep etc) and the zombies can't swim there...
Ireland might be a plan B if you're only a little bit rich? Quite a few Saudi's have their horse-racing operations here & own lots of land... Horses are food also! Although it might be an expensive steak if you paid a million for the whole horse!
