Stillman's Farm is offering two different CSA options for their 2010 season. Each box contains fresh produce from their New Braintree-area farm, the majority of which has been grown without the use of pesticides and chemicals. Only pick-up is available, from one of their seven locations. See their membership page for details: http://www.stillmansfarm.com/csamembership.htm.
They are also gearing up to be at a number of Boston-area farmer's markets this season: http://www.stillmansfarm.com/markets.html.
