The small farm dairy has been in decline for 50 years. About 10 years ago I took a road trip through part of central NC for the sole purpose of viewing the skeletal remains of a once thriving small farm dairy industry.
Mile after mile of abandoned and rotting silos and milk barns are still there.
Yes, I lived for a year in Upstate New York, in the center of what at least was dairy farm country. In fact, I had bought and lived in an old farm house (1876). Although we only had about 3/4 of an acre, a farmer who lived down the road owned much of the land around us. Our property was actually once his. Directly across the road from our front porch he kept some of his existing dairy cows. Anyway, he had subdivided much of the land he had owned and sold the properties as individual lots. He said the business had slowed considerably.
