As a Dallasite the area near to Lawton, as mentioned above, is a great break from the city. Dallas and Fort Worth aren't so far away for a relief from the sameness (unless you think four million cars, six million people and a metro area over 100 miles wide straddling three geograhicla regions makes for sameness), home to fine arts organizations, societies (concerts), theater, etc. But going west of Ft. Worth one passes onto the southern plains at which Ft. Sill is nearly center, once home to the greatest herd of animals on the planet; I recommend to you Walter Prescott Webb's, The Great Plains
; as well, J.Evett's Haley's book on frontiersman and pioneer rancher, Charles Goodnight.
Larry McMurtry lives just south of you in Archer City, Texas, and he has moved his book scout operation there. Must have a million books in three or four stores in that town. Read his, Walter Benjamin at the Dairy Queen
; and note his son, James, is a fine singer/songwriter. (Of course you'll recall his books made into movies, three or four or more now., Hud, Terms of Endearment, Lonesome Dove, etc
You'll need a few albums of Bob Wills & The Texas Playboys (western swing, which the group Asleep at the Wheel keeps alive today); some time at places like Albany, TX or other towns where the rodeos have the nearest thing to cowboys today. Country & Western was once a decent genre, the "westerness" is pretty much gone. Merle Haggard really ought to have been born there, and you'll find that transplanted Okies made the California Bakersfield sound that still pops up.
Gore Vidal did some growing up in Oklahoma as his grandfather was one of the first US Senators of that state; the history of that area as a state has all the ingredients for first rate reading (corruption, crime, and Kerr-McGee). There are a couple of giant ranches left in that area, so the plains wildlife you can see has some great ranges.
Of course, the thunderstorms are unmatched. Yanks don't understand and don't expect 'em to. You'll learn to read the skies like the rest of us, and you'll be prepared to move on or take shelter.
The rivers have a life of their own, the Red is as much a border in some ways as the Rio Grande; a sub-culture all along it.
Eastern Oklahoma is gorgeous. Lake Tenkiller, for one. Arrowhead. Will Rogers was born near Oolagah in the Nation (Cherokee) and taught by a freed slave some of his basics, still good today. Look for a book or two on the 101 Ranch (a Bill Cody-style traveling extravaganza and the Hollywood connection).
You might also enjoy books on the oil industry; the biography of J. L. DeGolyer; The Prize
, etc. Oil and gas production is still big in the area south of you. H.K. Bissingers, Friday Night Lights
Of course, Angie Debo. Live there awhile and western painting, literature, etc. ain't so removed. Try Joaquin Jackson's recent memoir on being a Texas Ranger, too.
Richard Avedon's photo book, The American West
[correct title?] and others can begin to give you a feel. It ain't about TV land and being (in the recent words of cyber-idiot Wm. Gibson) "connected" electronically.
Much is sudden. Little is hidden.
I'll bet that more than one AM station still precedes the 6:00 a.m. "Farm & Ranch Report" with Eddie Arnolds, Cattle Call
