I've never really wondered which parts of the country produce the milk I consume on a regular basis. But as the maps in this article show there are certain parts of country that are densely populated with cows for the sole purpose of producing milk. This article also indicates that the "cow islands" in the Southeastern part of the United States are becoming smaller, while the density of the "cow islands" in the Northern and Western parts of the country are increasing at a significantly steady rate. While reading this article, I learned more about where the most cows in the U.S. are producing milk and how that might affect the price of the milk I buy.

How would this relate to the Von Thunen model we discussed?
