seems like, for $30,000, one could replace many times a cow
that wanders off...

True story - newest GPS apps I have heard about recently:

1 - Cow Herding. Seems if you kick a cow's rump, and yell in
its ear, it will move ahead and "away" from the sound. So they
now have cowcollars with GPS tracking, a computer range
mapper, and stereo earphones. If the cow wanders, the computer
checks the GPS and yells in the appropriate ear to direct the
cow back to the proper range area. $30,000 per cow now, but mass
production will bring the prices down of course
