Well my co-worker is one: ex-military, java/python/etc dev. I can't remember how many head of beef, but I recall being impressed.

Come to think of it, another friend in Texas has 50,000 acres (family property) and would probably be in favor too.

Other significant land owners have independently introduced me to Mission Wolf... one has Yak I think.

Finally, I met Allan Savory not too long ago, and I'd wager that he would be happy to introduce me to wolf-friendly ranchers.
