Cows face north and south...

[shilala]

This was in the news just awhile ago.
Cows and deer (and other ruminants) tend to stand north and south.
I just saw some team of goobers building a great big magnetic field building so they can fool cows because they think cows have special magnetic field sensitivity.
Oddly, it didn't fool the cows.
I'm no scientist, but if I'm a cow, I'm gonna stand north/south to get some sun on that big fat belly so I can make good poop real fast.
When cows get hot, they lay in the shade. They lay whatever direction they want. Oddly, shade seems to have some sort of antimagnetic cow properties.

I'd like to ramp up the stakes a little bit. I'd like to see these scientists build magnetic fields over football stadiums to try to see why they all run north/south.
I'm guessing pigskin has magnetic field sensitive properties, too. When this gets out, Wes Welker will probably put magnets in his gloves. Or would that repel the ball?
It appears more tests are necessary.
