From the L.A. Times:
A growing number of farmers' markets are extending their operation into and through the winter months — even in cold-weather states like Massachusetts. The expansion comes as more farmers are prolonging their growing seasons with greenhouses and other methods. It's also fueled by an increased number of people who aim to eat locally produced food year-round.
"It can't be a five-month-long thing and then just stop and everybody go to Walmart," said Dave Purpura, a farmer who participates in the winter market at Plimoth Plantation, a living history museum dedicated to the Pilgrims. "If you want to be serious about promoting the local food economy, you have to go through the winter."
