Ok, I'm going to have to put an end to all the North American chest-beating about your awesome "survivalist" skills.
I live in Southern California. "You're screwed" you say. Not quite. Couple hours drive south and I'm in the wonderful land of Mexico. "How will that help you?" Easy:
1) People know how to survive without infrastructure. Now, while Mexico certainly isn't as underdeveloped as it is in the gringo imagination (freeways there are excellent, actually), there are still plenty of villages and towns that remain to a large extent "off the grid." Moreover, people have more experience and familiarity taking care of themselves without all the modern conveniences. Especially the further south you go, heading into Central America. Which means I can still enjoy delicious enchiladas, while you all are eating bark or worms or whatever.
2) Guns. It's well known that any zombie apocalypse will involve primarily low-tech warfare. Now, all your awesome F-18 fighter jets and B-52 bombers are completely useless without the maintenance, logistics, and fuel needed to get those things in the sky. In Mexico, on the other hand there's this:
With the complete collapse of North American drug markets, my guess is the cartels and the military will start working together to repel the zombie threat. Who's the man being carried away you ask? That's Chapo Guzman. He literally was on the run from the military for years, using secret escape routes and tunnels in the drainage system of the town he was hiding in. If any group of people is going to know how to repel a zombie invasion with plenty of stored up ammunition, I'm going to go with these guys.
3) Communal solidarity. Now, Americans happen to be, as one person once put it, "pathologically individualistic." That's great and all if you can hole up in Starbucks and get on the freeway to go back to the suburbs when you're done working on your social media startup. Elsewhere though, people live in more communal settings. Having a community around you isn't such a bad thing (assuming it's not the site of the original outbreak), as you can develop a division of labor. Do I know how to take care of myself in case of a zombie apocalypse? Probably not. But what do I get from doing it on my own anyways, other than to puff up my chest? Nada.
Entonces gringos, ¡que todo se vaya bien aqui en los estados unidos! Yo, me voy a Mexico.
