Head off to a farmhouse somewhere, probably. Or lake country. Dunno about food as the growing season is only a few months here, but I guess you don't need to worry about Zombies at -40.
I do have a standing invitation if I can make it out west to the Rockies. However, best bet would probably be lake country, cabin on an island. Raid other cabins for food/weapons, and get a lot of flower pots so you can grow stuff inside by the windows.
... I've been meaning to take Archery back up again. My sister and I have always considered making a survival kit.. but if it hits in winter (or just before winter), things might get rough because you don't have time to explore/barricade and such.
Or we just off each other. That's an option, too.
... Now I want to play ProjectZomboid or something.
... I'll just go check and see if State of Decay has any news updates.
