From Bushland, TX (a few miles west of Amarillo on I-40), go north on FR 2381 about 6 miles, then NW on FR 1061. The northwest end of the route is intersection of FR 1061 & Hwy 385 near Tascosa. This is a great alternate route between Amarillo and Raton, NM.
As you start north from Bushland, you'll see nothing but flat -- just like you were seeing on I-40. However, about 3 miles north, the road will suddenly dip behind a hill and drop you into a canyon that starts twists and turns, ups and downs that don't end until you reach Hwy 385.
Scenery is mesquite trees and ranches, but it's the canyons, bluffs & sudden vistas that make it special. Be watchful for deer, jack rabbits and other wildlife -- even the occasional rancher on a horse!
Road is two-lane, usually well-maintained, lots of gentle curves, hills & valleys. Traffic routinely runs 65-70mph, and traffic is usually light. The stop sign at the intersection of FR 2381 & FR 1061 is the only one on the entire route.
There are no roadside amenities at all between Bushland and Channing. If you have trouble, the local ranchers are typically courteous and helpful if you approach them politely.
