Eating local in winter - followup

Forgive me for neglecting Just Hungry a bit this week - I've been spending all of my free waking time in Knightsbridge. I did want to follow up on the thoughtful comments left on my post about eating local in winter, in areas without 4-season growing conditions. Perhaps because I've been immersed in the 14th century has helped, but I'm increasingly intrigued by the idea of trying to experience how it would have been like to survive the winter in an age when fresh foods were not shipped in from far parts.

So I am going to try it out for at least a week in a few weeks - I think the end of January/beginning of February would be a good time. I don't think I will go back as far as the Middle Ages, but something prior to the 19th century anyway - prior to fast trading ships as well as the advent of refrigeration. (I'm not sure if I will aim for pre-canning days as well). I'm also a bit undecided as to if I'll try to emulate how it would have been in Switzerland, or something more generic, as well as what class in society I'd put myself (since rich people would have eaten a lot better then poor people, of course). When I've done more research into this I'll post what I'm going to do.
