Simons' Farm Market, Rt. 1, Ellsworth ME
A wonderful farm stand that's been here as long as I can remember. They grow a huge variety of vegetables, and what they don't grow, they choose the very best to sell. There are no other places in Maine where I can regularly count on being able to find both green and black figs. They've recently expanded to include locally-grown natural meats, locally baked bread; preserves, relishes, honey, maple syrup and cheese - including a fantastic local ricotta salata! Since it's on our route to our house in Gouldsboro, we always stop at Simons' first and plan our dinner on the spot.
Good local produce is cheaper and better than what you'll find at any mega-mart, even trendy ones. Buying from these places supports your local economy and local agriculture.
