Time has a nice profile of Madeleine Pickens, wife of T. Boone Pickens. She's trying to start a wild horse sanctuary -- but faces stiff opposition from ranchers and the BLM:

Her giant ranch, in northeastern Nevada, is spread across three valleys and two mountain ranges, and Pickens intends to turn it all into a wild-horse sanctuary, or as she calls it, Mustang Monument. The first arrivals are 500 horses she bought from a Paiute Indian reservation. The horses, she says, would otherwise have been slaughtered across the border.
