True Burson tosses a hoolihan loop on a young horse at the Four Sixes Ranch. I went to the Guthrie, Texas, ranch to get photos of True and his brother, Dusty, starting colts. In the April 2015 issue of Western Horseman, we ran an article about the three Burson brothers who all work on big outfits. Zack, the eldest, works on the Bell Ranch in New Mexico.
