There has been a proliferation of farmers' markets in the region over the past few years. This is a great step back to the days before superstore supermarkets. Imagine, moving backwards! In this case, I think it's a great idea. Several other recent movements in farming are "Eat Local" and "Community Supported Agriculture," often referred to as CSA. Click here to learn more.
The 2012 season is beginning, so you can look forward to about 6 months of farmers' markets to attend! For a listing of New Hampshire markets, click here.
A good companion book to farmers' market shopping is Farmer John's Cookbook: The Real Dirt on Vegetables by John Peterson.
