Country living has problems already. There are a lot of really marginal people living out in the boonies now. Life isn't going to get any better for them if gas goes up. They don't live in little self-sufficient farmsteads. They live in 40 year old trailers and on marginal land that can't be farmed. Most have forgotten how to grow a garden anyway.
They are losing their jobs and living on next to nothing. I heard about a guy who was burning the house to stay warm last winter. He had a chainsaw and was cutting pieces of the house into stove sized chunks.
Life around here is not going to be a picnic post-peak. It's hard enough now.
