I live in the Northeast of the US, where the growing season is from spring to late autumn. We have TONS of local farmers and I do eat a lot of locally grown food during those months. Everything from leafy greens and other veggies to fruits in season like berries, apples, pears. I am a member of a community farm and get my stuff directly from the farmers. However, some of my staples (avocados, bananas, oranges) don't grow in this region, so that stuff I eat imported.
I don't feel guilty about it. I figure my health is as good a reason as any with respect to the use of petrol for shipping things long distances.
If I were trying to eat a raw diet strictly on locally grown food, I would move to a climate with a year-round growing season. The thought has crossed my mind.
Otherwise, I don't see how eating raw/locally would be possible unless your diet in the winter months consisted solely of sprouts, fermented raw foods like kimchee, dried or frozen foods and anything else that could be preserved longterm.
