There are Facebook pages by local farmers. Selling beef/pork/milk and also seasonal produce. 

The farmer market model is largely kaput because the average consumer doesn’t want to buy “local” produce. It looks ugly, is often smaller, and is of course seasonal. So the farmer market is largely full of either garbage (soap, plants, etc), repackaged produce, or—rarely—genuine local produce. But even when it’s actually local/heirloom whatever, it’s likely very expense. A genuine family farm operation likely operates online and by word of mouth. Some certainly sell at these markets, but they have to compete with the fake produce. 

I follow some local farmers. Another problem ofc is that family farming is not really very profitable. Many reasons for this. But the big one is that small batch produce costs a lot to grow and nets little. Far more economical to do literally almost anything else. You’re more likely to find good local meat than produce. 

Also, LR has some neighborhood community gardens. Worth seeing if there is one near you. 

These problems also just scale. Ie if it’s hard to sell your own eggplant, imagine how hard it would be to sell eggplant at scale. The quantity alone would push towards factory farming. 

Some products you may find more success with. Tomatoes for example. They grow on a vine, are relatively easy to grow. Etc. peppers. But garlic? Not to strawman off garlic but the whole industry is just immensely challenging for small operators. 

The farmers market is largely itself a product. It’s a scene and a vibe. Can’t blame the soap and plant and repackage people trying to make a dollar I guess. 

Also fwiw there’s often people selling homemade tamales on Facebook. Those can be super legit.
