Wild horses at the Prairie National Wild Horse Refuge, Bartlesville, Oklahoma. Established in 1989, it is the second wild horse sanctuary in the US. The privately operated enterprise partners with the Federal Bureau of Land Management to care for about 2,000 wild horses, most of which are too old and defiant to be adopted.
