The First Rule of the Zombie Apocalypse: You will NOT be staying in your home.
There’ll be no electricity, no water, no cable, no internets and no guarantee that your house is remotely zombie-proof.
The Second Rule of the Zombie Apocalypse: Find a defensible shelter.
Sleeping under the stars is a good way to get nom-nom-nommed. Even if there are not walking dead around to eat your brains, other survivors will happily steal your stuff and leave you for dead.
Here’s a great little shelter from the British, who have glorious accents, making anything they say or invent ten times the awesome.
It’s an inflatable shelter made from canvas impregnated with cement*. Blow it up, spray water on it and bam, instant bomb shelter.
This is military grade stuff. Pile dirt around it and you’ve got an instant bunker that’s safe from small arms fire, mortars and the undead.
*Yes, the video says “concrete.” Cement is actually the right term. Concrete is cement mixed with rocks and whatnot.
