A teacher from Cleveland came to the farm we’re at in mid-Ohio on Saturday. He dug in the garden and spread many wheelbarrows of mulch around. At one point, this teacher looked at me and said that each horticulture class he has his city students grow something in a styro-foam cup. “And they think it’s a big thing,” he lamented. I couldn’t help but think that if you’re pretty much surrounded by warrens of brick buildings, webs of concrete pavement and are growing a bean plant in a styro-foam cup, not only aren’t you grounded in much — but you may be on the edge of insanity and not even know it.
