Two questions--
1) In the book it is suggested to eat produce which naturally grows in the climate where you live. So, clearly I want to limit things like citrus fruits. Our growing season is long enough to grow most other things in the summer. For instance, cranberries, heirloom apples, cherries all do very well. We've been very successful with squash, collard greens and Swiss chard in our own garden. But if I want fresh produce year-round it will obviously be shipped in from somewhere. Is this still considered an item from my own climate?
2) If I am going to eat produce shipped from warmer places, and their peak season for 'whatever' is 3 months ahead of what it would be here, is that produce still considered in-season? I tend to think yes because it had a naturally growing cycle in the environment it came from. Am I on the right track?
