I live in California. Most everything is grown here anyway so it's almost always local produce even in the big grocery stores. Some of the farmer's market stuff is exactly the same stuff as what the grocery stores have. Not everything at the farmer's market is organically grown, either.
What I go for are the little gems you have to hunt for. Like there is one farmer that sells all kinds of unusual greens and herbs you can't get anywhere else. Another has purple carrots. A few farmers bring in grass-fed and pastured meats you can't get anywhere. Other things: Goose eggs, unusual nuts, strange tropical fruits, peaches you can eat today and not take a risk they'll only end up mealy, truly local farmers as in down the street local, not Coachella Valley local.
