You're a couple of weeks too late for me to link to the photos of the folks who attended the ball. The Tyler newspaper dedicated a full page to the event that included a bunch of photos. Everyone was dressed in their western finery. They even had several photos of the custom boots some of the people were wearing. Let's just say that some were flamboyant!
As far as transportation, they didn't show anything along that line, but Escalades, Hummers and all kinds of pickups would certainly be in the parking lot. Most cars would be big American brands...Lincolns...Caddys...Chryslers.
This part of the state doesn't have many canyons or rocks, but most of the state has cactus of some kind. We have prickly pear, but nothing very big. The larger cactus are found more to the south and west. We're only 90 miles from Louisiana, so we're more apt to run into a swamp than a cactus.
Most of the state is also subject to heavy rains, mostly in the spring, that cause flash floods. Usually, the flooding doesn't last very long and unless a bridge washes out, the roads are mostly passible soon after the rain stops.
The area around Wichita Falls is quite flat and not very pretty. I have a good friend who owns a small ranch about 20 miles out of WF, and his land is mostly scrub brush and mesquite. Creeks and rivers in the area are quite shallow and wide, whereas in areas where there are more hills, the streams are deeper and faster running. Running water of any kind along the Oklahoma border is very muddy because of the red clay. That silt fills the slower moving streams and rivers, which also helps make them wide and shallow.
I often see the cowboys working the neighboring ranch, and you'd think you had gone back a hundred years in time. No 4-wheelers or baseball caps. Rain, shine, heat or cold, it's hats, boots, spurs and chaps when they are with the cattle or riding a fence line, and I've seen them carrying a new calf across the pommel.
They have a couple of beat-up old Dodge trucks to haul feed from a big tank out to the feed troughs, or to go into town for supplies.
Most of our ranch houses and yards are nicely kept and the grass is mowed regularly. You'd probably see a bunch of crape myrtles and other flowering shrubs around the ranch house. Every ranch would have one or more man-made ponds, or "tanks" for watering the animals.
One thing we have in this part of the state is an abundance of wild hogs that can get nasty. One guy I talked to said a friend was treed by a sow with a litter. Something like that might figure into a story.
