The biggest farmers market in the United States - Dane County Farmers Market, Madison, Wisconsin. Open all year long on Saturday and Wednesdays in the summer. All items are produced locally by the vendor behind the table. They even have a breakfast served from 8:30 am till 11:00 am.
There is craft and single food item sales across the street from the farmers market. The farmers market is BIG, so bring some good walking shoes! Bearwiskers says Yum Yum.
