How do you grow food in the mountains??? How do you grow enough feed for stock??? All of the places where you can do "this", is already taken, and folks already live there.
Do you actually think this idea is some kind of secret?? Find a cave, move into it, see how long you can live without outside support.
I live in such a place, I still have snow on the ground this very day, and yes the Arctic Blasts DO affect our weather, usually with unbearable cold, and frozen pipes.
Prep, but know your limitations.
