in all seriousness though, a prison would be a good choice. like vagrant said, not only are there secure vehicles on site, but layers upon layers of barbed while fences and walls for them to try to get through. and with a few power tools, you can take off all the cell doors to fortify main entry points. not only that, but there would be guns and ammo left behind by the guards, and there would be a large amount of food. in the event that they did break in, you could always head to the roof, when there is likely a helipad in case help arrives. and im pretty sure all prisons have generators...
while those are great ideas, everyones forgetting that they will probably already be filled. and most likely wont want to take you in because of trust, or having too many people already..
anyone watch that show the colony on discovery channel its pretty good and sorta similar to what survival would be like in a post apocalyptic world run by zombies. Its on discovery every tuesday at either 10 or 9 pm
question: do zombies feel pain, because i'm going over the designs of my shelter and trying to figure out how helpful barbed wire will be. thanks
