I think that the worst place to live would be in a big city. I think that, especially for a family, the only reasonable way to live is to get food locally within a small community that is working together.

I am interested in how we view and value work in smaller communities - it makes you wonder how much of our modern techie and white - collar skills have become useless. If you live in a big city, your work is abstract as are your skills. But in the country, the vale of a good chainsaw quickly outstrips the value of a laptop.

Perhaps my small - town bias has completely negated my ability to see the benefits of the city.
