 The ranch is also home to one of the few remaining recognizable sections of the Mackenzie Trail, which was once the primary route for wagon trains traveling from Fort Griffin near Albany in Shackelford County, Texas, to Fort Sumner, New Mexico.Much of this land is now used for farming.When the Thompsons purchased the Triple Arrow in the late 1980s, another interested buyer had planned to turn the acreage into irrigated farmland.
