From Megan McArdle…..

If you want to know just how ridiculous our agricultural programs are, consider this: for about half a century, we priced milk based on how far the cow was from Eau Claire, Wisconsin. No, I swear, I am not making this up. Apparently, the USDA scientifically determined that Eau Claire was the perfectest place in the entire world to keep cows, and that therefore the farther you were from that fabled city, the harder you must find it to produce milk.
