I have tried--barring other engagements--to make it to the farmer's market every Saturday this season. I've done pretty well and only missed a couple. What really blows us away are the local heirloom tomatoes. We've been buying at least 2 lbs of heirlooms a week and putting them in salads, in sandwiches, and eating them plain with salt and fresh ground pepper. We typically do the majority of our shopping for produce at the farmer's market; we easily spend at least $20/week there. We live in an area that is really at the forefront of the local food/slow food movement and is also a good agricultural area. At the market, we buy not only produce, but salsa, bread, jam, and honey.
Here you can see some photos of the bounty of our market:

Lucky for us--the bounty doesn't go away come winter, it just relocates; there's an indoor winter market that runs almost all winter and features some of the best apple cider I've ever had. Though the selection at the indoor winter market isn't as bountiful as the outdoor summer market for obvious reasons, we can still get all of our favorite heirloom potatoes (that's right, heirloom potatoes!) and other root veggies, as well as that delicious apple cider and artisanal local sourdough.
There is no greater pleasure to me than shopping at a farmer's market. Seriously. As a foodie, it is paradise.
