Pack light, only what is necessary, hole up with lots of sterile people and pool together our food, when winter comes and Zack freezes, raid every building we can for more supplies. During winter, if we made it, we would fortify our whateverbuildingwearein stronghold with punji stakes, a retractable bridge, and brick up every window/door except one. A pit surrounding the building would be filled with punji stakes, no Gs will make it across. The only way we could die is before the first winter or by our own, due to arson or psychopathic violence. starvation probably wouldn't be likely, there's enough to catch and preserve in the winter to last a few men a year.
