I went to an indoor farmer's market last Saturday and I was impressed! Located in the basement of a century old dairy barn on the Greig farm property, not only were there farmers and bakers who also frequent other markets, but there were a large number who were new to me.
This is a year round market open on Saturdays from 10AM to 3PM; I was also told that during the summer they plan to expand outdoors.
Here are two links that explain more:
In conclusion, I feel that this market may rival the ones in Rhinebeck and Kingston--the two best in the Hudson Valley.
