A farmer friend of mine told me recently about a busload of middle school children who came to his farm for a tour. The first two boys off the bus asked, "Where is the salsa tree?" They thought they could go pick salsa, like apples and peaches. Oh my. What do they put on SAT tests to measure this? Does anybody care? How little can a person know about food and still make educated decisions about it? Is this knowledge going to change before they enter the voting booth? Now that's a scary thought.

My advice to anyone who wants to join in on farming is diversify. Nature is diversified, and I know you'll always have a core thing that you'll really like, but hang stuff around the edges of it. It will make your place more interesting for people to come to, and it's a lot easier to sell something else to an existing customer.

If you have to put on a haz-mat suit to visit a farm, you may not want to eat what comes from it.

A farm includes the passion of the farmer's heart, the interest of the farm's customers, the biological activity in the soil, the pleasantness of the air about the farm -- it's everything touching, emanating from, and supplying that piece of landscape. A farm is virtually a living organism. The tragedy of our time is that cultural philosophies and market realities are squeezing life's vitality out of most farms. And that is why the average farmer is now 60 years old. Serfdom just doesn't attract the best and brightest.

Amazingly, we’ve become a culture that considers Twinkies, Cocoa Puffs, and Mountain Dew safe, but raw milk and compost-grown tomatoes unsafe.

If every American for one week refused to eat at a fast-food joint, it would bring concentrated animal feeding operations to their knees.

The notion that processed food is cheap and integrity foods are prohibitively expensive is simply not true.
