Let's start with one you might already know.
It would be easy for one to laugh reading this. However, taped to the glass nearby it were several photographs of destroyed cars that had struck said Invisible Cows. They might be invisible, but they sure have a hell of a lot of mass. They have mass out to here! Those cars looked as if they had struck giant living walls of unyielding flesh. Er, I guess that pretty much sums it up for the whole cow situation.
The thing I'd hate to do is make the call back to the rental agency. "Excuse me, but in addition to driving across the Saddle Road, which clearly violates my rental agreement and driving up Mauna Kea, which also violates my rental agreement, I have maintained my simple state of idiocy by running headlong into a frickin' cow. Please come and remove what used to be a vehicle and also if you can, donate my brain to science as one of those 'How did such a creature actually live?!' kind of exhibits."
