Small dairy farmers are going bankrupt by the thousands, largely due to declining milk prices. Keeping the cost of production low is one of the keys to staying solvent.

We have our own way of moving cows in the South. First you blow the horn on the old jeep, then yell, "Come on girls! Come onnnn" and they will follow you anywhere. Call your lead cow by name and she will call the others . "Alright Tess, bring em on".
