Well, here in central Illinois, if eating raw and locally grown, you'd be living off of sprouted grains and legumes for 6+ months of the year. You could figure on apples for about three of those months, and carrots for maybe two, if you have a really good root cellar, but for part of that time they're no longer very appetising raw. In a good root cellar, potatoes can last up to four months, but again, by that time you have a lot of rotten ones, and what's left isn't very appetising even cooked.
I'd be very interested in meeting someone who does actually eat raw and locally in even a region 7 growing season, much less a region 6 or shorter.
Weeds, BTW, are gone after the first hard frost, and there's very little to be found in edible weeds before late April. (There's some up earlier, depending on the spring, but the plants are very small, so you need to cut a lot of plants to get anything.)
