Besides the drought, many acres of corn are now going to ethanol production instead of food. This isn't impacting the US only. In the southwest, the drought is going to continue so those prices are only going to get higher. Have you ever seen them really drop to prior levels? Dogfood has dropped from a #40 lb bag down to a 33# bag and the price keeps inching up.
Between price and value conciousness, food safety and food politics, I have probably changed my buying habits more in the last 5 years than in the 40 plus consumer years before.
With all of our running and all of our cunning, If we couldn't laugh, we would all go insane...
