My guess is DFA took the most populated cities, and left the rural ones to fend for themselves. I can't fault them it makes sense.
Also in looking at the 2 other big milk companies that I know of, they pulled out of the cities that were already occupied by them, Borden and Prairie Farms. I
don't know how PF is doing financially, however it sets the door for a merger for the southeast markets. Here's hoping!
