Cheyenne River Ranch buffalo roam freely on thousands of acres of native grasses. The ranch is owned by Dan and Jill O’Brien with a focus on grassland restoration and humanely harvested meat sold via Wild Idea Buffalo Co. Dan has been a wildlife biologist and rancher for over 30 years and is author of Buffalo for the Broken Heart: Restoring Life to a Black Hills Ranch.
