As Max Brooks has told us more than once, no one who stays in a city will survive the zombie apocalypse. From the threats of the undead themselves, to infrastructure and supply issues (food, water, etc), to the madness that comes from the constant groaning filling your ears, to the disease that'll arrive with all those dead bodies lying around (hello, cholera): well, you'll want to bust out of town as soon as you catch wind of the first terrible bite.
Just in case you need a tastefully attractive reminder of which way you need to go to get the hell out, Laughing Squid points us to Design Different, which has created a charming set of Zombie Safe Zone maps intended to help you chart a course out of your city. Per their website:
The zombie apocalypse has finally happened and you need to leave your city fast! As panic sets in you quickly remember that to survive a zombie apocalypse you need to find a safe zone, somewhere where there's a natural abundance of water, fish and forestry. Somewhere far away in an isolated area. You decide to Google map a location to search for a safe zone but WAIT, all systems are down. How do you find your safe zone!
Each item in their map collection, which they say is focused on the cities most likely to have an outbreak of the undead, includes "directions, distance, time, and additional information about the safe zone like water type and food resources."
But it's not all survival, as the maps come in six sizes and nine colors, as the apocalypse is no reason to forget about design.
The map for San Francisco guides us way up north to Shasta-Trinity National Forest, a 5+ hour trip to an area that generally only allows camping for 30 days, and requires pets to be on leash at all times. Presumably rules like that, and one prohibiting the "discharge a firearm or any other implement capable of taking human life, causing injury, or damaging property" will fall by the wayside when the dead walk the earth. See you there!
