F.M. 293 west to Texas 136 north provides views of modern High Plains agriculture contrasted with traditional ranch lands unchanged for centuries. Precise row crops are left behind as route enters rolling grasslands of broad Canadian River Valley. Fascinating historical marker beside Texas 136, some 10 miles north of F.M. 293, marks portion of trail that wound from Fort Smith, AR, to Santa Fe, NM. Though now covered by grass, wagon ruts are still visible. Texas 136 leads north to Lake Meredith and popular federal recreational areas around it (see LAKES listing).
