Portland Farmers Market's flagship keeps its Saturday rhythm all winter in the South Park Blocks on the Portland State campus. The winter market is smaller than the summer crush, which makes it easier to talk with the farmers, bakers, ranchers and cheesemakers who still show up in the cold. It's the one Portland Farmers Market site open every Saturday through the season, closing only on December 26, so it doubles as a dependable stop for holiday baking supplies and Sunday-dinner ingredients.
