Did We Run Out Of Cows??

I know the pork increases are a result of a virus that hit the young pigs. The milk however seems to be a secret. It's unlikely to have anything to do with grain, but alfalfa is a different story. It was somewhat of a surprise because we generally get news reports when hay supplies becomes weak.
I wish I could by milk at gas prices, $3.20-$3.50 I can live with for a gallon of milk.
