 The brother of a friend of mine raises yak in western Nebraska.  I've been
 eating yak for about a year.  Wonderful stuff.  Better than beef
 by far, better than buffalo.  It's lean and sweet-tasting.  I believe it is
 totally grass-fed, though I'm not sure.

Talking of yaks - go and see the movie "Himalaya". Apart from being a great
movie, it also shows how healthy and sturdy people living on traditional
diets can be.
