Hey, Roger.
You're right - I couldn't think of his name to save my life, but it was Joe Warren - Joe's SIL, Larry Bailey, over on Amos Hamlett Rd.(his farm adjoined the place we owned), also had beefalo - but his weren't 'dog-gentle', by any stretch of the imagination. K.Kressenberg, who was up toward the back side of Milky Way had beefalo with a Red Brangus base (and I worked on one 3/4 Bison-1/4 Brahman cow for her- one time; WILD and CRAZY!!!).
Seems like Mr. Witt, up on Yokley Rd., told me that Joe W. was raising Gelbvieh/Balancers - but that was a number of years ago; he may still have beefalo, or may have moved on to yet another breed.
TT - I've been gone from Giles Co. for 20 years, but to me, it's still the prettiest place on earth.
