Back in the 30's and 40's, Helen and Scott Nearing did this in Vermont (I
think). They wrote several books on the subject, most of which are out of
print I suspect but you might still be able to find them. They were kind
of anal about their style of living but they raised all their food in a
couple of gardens on their property AND did it on a rigidly defined ration
of a half days work. The rest of their time was devoted to their cause.
