Fun fact: Have actually seen one of these cows up close and personal at UC Davis. It's impressive, however I passed on sticking my hand in: the lady in line before me was hit by a jet of digestive products from an ill-timed stomach contraction.
Didn't they have a thing during Picnic Day where you could have seen and been near those cows??
IT wouldn't surprise me if they did, but I didn't notice anything about it when I was in Cole.
