Read the letter here at La Vida Locavore.
They refer to modern industrial farm practices as "conventional" in the letter as if organic were some kind of new fangled trend for urbanites. It's actually the way that food was grown for the majority of human history. When the older people in the church found out about what Nancy and I were up to they said, "That's how we all used to live." Local, resourceful and not so dependent on the harvesting of energy from fossil fuels. I'm not against chemicals but jeesh, no need to get defensive.
