Our local farmer's market recently expanded their operation to Saturday and now Wednesday mornings, so we have a better chance to make it down there to pick up some fresh local veggies and support our local growers.
The farmer's market is what it is. You won't find the selection that you would at a Mega Mart - no bananas or mangoes... which is kind of the point. You will find a nice selection f the stuff that grows seasonally in your part of the world. For us, right now, that means lots of onions, garlic, potatoes, tomatoes, turnips, herbs of all kinds, green beans, berries, squash, honey, sorghum, etc...
We got the fresh blackberries, above, and they were delicious. We also got some tomatoes that were not around long enough to be photographed before they were gobbled up.
Like I was saying, the only drawback is the narrower selection, but the benefits are many; very good produce, very little packaging (about as little as you like), very little transportation cost to move the product to market, local profit rather than corporate profit. If I can't grow my own (which I can't right now) I'd much prefer to give my business to these neighbors of mine.
