I'm not sure how close to I-40 you intend on staying the route, but Mountain Ranch in Fairfield Bay, and Tannenbaum in Drasco are outstanding courses with great views. Each are about an hour north of Little Rock. Definitely worth the detour, according to me.
I had the fortune of playing Tannenbaum a lot before the entire 18 was finished and it became more popular. We'd play 9 twice until they started slowly opening holes on the back 9. Great views of the mountains and Greers Ferry Lake.
If you're determined to stay around I-40, Eagle Hill in Little Rock is worth your time. Not nearly as nice as the above, but an overall good course.
Enjoy!
Hogs suck, Horns suck, everyone else I can deal with.
