If you are interested in talking to the farmers that grow your food, you have to shop at your local farmers' market. It is the best way to learn how your food is grown and always cool to meet the folks that grow it. Farmers often share great tricks for storing their (and soon to be your) produce, sometimes they offer up great cooking techniques or favorite food combos.
If there is agriculture within 50 miles of your town, the chances are high there is a farmers' market nearby. I just found this super thorough listing of markets, organized by state and city, that was put together by the USDA. So if you are concerned about the carbon footprint created by the food you eat and are following the 100 Mile Diet you should really shop your local market. Chances are high that the prices there are lower than at your local grocery store. Plus you know the produce has just been picked so it will be super fresh and super nutritious.
This is great. I have attempted to do this, the only drawback is sometimes I feel they are charging way too much. I also read an article on Whole Foods which I have a love/hate relationship with, that said they often do not use local farmers produce but will instead bring produce from faraway countries. This in turn jacks up the pricing and does not support local farmers.
So do you pay expensive local farmers or pay expensive Whole Foods? I'm paying one of them because I like buying good food...
