U.S. 160 west of Medicine Lodge:
Salt Fork of Arkansas River and cliffs in the midday sun.
Clever use of solar energy to water cattle.
During your visit, have lunch at Buster's in Sun City with real cowboys. Yes, the ranches in the area have brands (jump down to final photo for an example) and there are chairs with the ranches' brands.
The Lazy K brand of the Merrill Ranch in Wilmore. The cattle here roam the open range...no fencing them in.
It is an area of unexpectedly spectacular scenery. The photos above are mine. You can see even more photography from the region here.
