I was pleased to discover that the Dane Co. market is open year round (except for two weeks at Christmastime). In the winter it operates on Saturday mornings at one of two indoor locations.
The indoor market is smaller than the summer grouping, but still fairly large, and many of the same vendors participate. Today, I bought some remarkable aged raw-milk cheese, some lovely red-leaf lettuce, tomatoes, winter squash, daikon radishes, carrots, fingerling potatoes and a jar of freshly made horseradish. There were lots of root veggies, fresh garlic, greens, apples and other autumn produce, a good selection of baked goods, several meat and cheese purveyors, and perhaps more I didn't see because we got there 30 minutes before closing.
I thought prices seemed a bit costlier than I remembered from the summer market, but it's still a very good value. (Not nearly as pricey as Green City Market, for example.)
