A corn crib
Along a country road, we spied an enormous corncrib in really great condition!
Ontario farmer's have always grown acres and acres of field corn. (That's what we use for animal food, cereal, cornmeal, and now they distill it for gasoline.) A farmer would pick the ears of corn when they were mature enough, chop up the stalks for more animal food, or bedding and place the ears of corn in one of these open air 'cribs' to dry or to stay dry until he wanted to use them or sell it by the bushel.
