Magnificent! He's named Porter as in Porterhouse steak? I read they were domesticated 10,000 yrs ago. That's a long time to get them tame! Probably more a part of peoples lives then than cellphones and computers are today. Wild yaks might as well be a different species. So cool! Twist can wear his new yak hair shirt while doing trick riding on Porter. We've got big plans for you, Twist!
