saying that cow like pasture is you projecting you values on them. People study cows and near as they can tell cows don't care about wide open. Cows are herd animals and if they get plenty of feed in a barn with a few hundred other cows in their herd they are happy.
cows only moo when they are unhappy. I've been in barns with over 1000 cows and they are nearly silent. Cows in the wide open pasture moo all the time because of things they don't like.
