Humongous Farms?

Marcia Taylor at  DTN has a post on really big (where's Ed Sullivan when you need him) farms:

Giant farming companies--those with 250,000 acre scale and up--may be a new phenomenon to us, but they already are changing the competitiveness of global agriculture. Whether such scale can succeed here is still a big question, but it's becoming the norm in the former Soviet Union, Brazil and Argentina.

The current setup of the farm programs is something of a handicap to such large farms in the US, but as a commenter notes, changing over to crop insurance with no payment limitations would change the parameters. If such farms do come to the U.S., there won't be many towns left west of the Mississippi, at least not farming towns.
