I have visited Clayton many times. I am a horse rider, outdoors lover.
Here are some links:
This place is about 6 miles from Clayton, be sure to check the pics:
Welcome
Here is a link about Jeep trails:
SWFWDA Kiamichi Mountains 4WD Trails, Clayton, Oklahoma
Here is one about fishing etc.:
Oklahoma lakes, Lake Sardis Fishing Guides, Fishing Reports, Maps ...
Couldn't cut and paste this next part or make a link so I will just summarize this government report:
Pushmataha was the name of a Choctaw leader. Antlers, the county seat has manufacturers of products like custom mixed concrete, roof trusses, building materials and sportswear. Tourism and recreation are major parts of the economy, and agricultural is a basic component of the economy. The principal crop is wheat. Tuskahoma, noted for its fine architecture, was the last capitol of the Choctaw Nation.
As for shopping in Clayton, mostly that is the Dollar Store. I think there are two grocery stores. There is a pawn shop that sells guns and fishing stuff. There is some logging taking place on [SIZE=-1]Weyerhaeuser land. Government work is a big source of employment. There is a cute bed and breakfast near Indian Mounds Camp. There are several cafes that serve down home food. It was a big deal a couple of years ago when the rural water lines were extended, because it is difficult or impossible to have a water well.
Hope this helps.
Oh yeah, this is how locals in the area keep city slickers from moving there:
