the local rag published an article about trying to have a mostly local Thanksgiving dinner back in October. it is a good overview of the considerations involved in attempting to eat locally.
the article is saved here in the Honest Farm website. they are an organic farm about 20 minutes away from me.
another local farm, Elmwood Stock Farm is also working under the organic and sustainable model. I've participated in Elmwood's Community Sustained Agriculture (CSA) program for the last two years and plan to participate again this year.
