I spent several winters in rural Wisconsin, which I absolutely loved. There’s plenty of hunting and fishing, and because everyone hunts, they’re not reckless with their weapons. There’s also an abundance of firewood. Enduring sub zero cold (particularly in an ice age where spring may not come for a very long time) is a matter of personal constitution (I certainly don’t mind it) one should definitely factor in the snow plows. In the area I lived, there are residents who have plows that affix to the bumper of their trucks. Then they collect a small fee from the town. Neighbors in that region are definitely the type to pool together to keep those gas tanks filled. Everybody gets together for example to shovel the walkway outside a wheelchair bound naighbor’s house. It’s that kind of place. It may be cold as hell, but the people are warm. Something I would definitely factor in.
is that if you are looking to live and sustain here after any sort of crisis procuring meat long term might be hard. The deer population is down significantly because the laws have favored the wolves. So there is no hunting season for wolves and they have decimated our deer population, at least here in the northwoods. In the lower portion of the state there are more deer but CWD is still alive and hurting populations in probably every state at this point.
