The northern end just south of Jasper AR is very steep & winding. If you go that way stop at the top (you will see a tower that is wood)on your right - look east north east that is the area my wife grew up in. When you leave there go down very carefully - I don't post this to scare you from using it but to make you aware of the road. Yes, there is one run away ramp near the bottom of the mountain just before Jasper, AR.
