So the law is stupid.  Big, F**king Deal.  To quote from the late Justice Scalia:  It is possible for a law to be really stupid but still constitutional.

And if these two were looking at their own herds, then they would as I understand the matter, not have run afoul of the law.  But that is not what they did.  They started a business of using ultrasound to determine whether other farmer's cows were pregnant and did so without having a veterinary license, and when they were initially called on the carpet for it, they chose to not pursue changing the law - which would have been a rational thing to do - but instead chose to thumb their noses at the law.

Rules of holes...

It's definitely coming. Whether or not it happens before I leave I cannot tell.
