Have you noticed what is happening with milk prices? If you've got kids, this is a bigger concern than gasoline prices, although, as it turns out, it is directly related. Up until just a few days ago, the cheapest milk we could get was at the local convenience store for $2.50/gallon. This was even cheaper than Walmart. Now, the convenience store price is $3/gallon and Walmart is $3.38/gallon. Organic milk prices have always been high ($5/gallon at Target a couple years ago), but now they're outrageous (Walmart's price is over $7/gallon). And you thought gas was expensive!
I have it on good authority from my nephew in the business that farmers are storing their corn waiting for the prices to go up as a result of ethanol legislation. So, now consumers are not only paying more at the pump, but apparently the corn shortage has driven up the cost of feeding dairy cows. This is what happens when environmentalists and the government diddle with the free-market.
