I had drove this road MANY times back in the mid 80´s when I worked in Huntsville, AR for 6 months.
Revisited this road on my motorcycle in 2014 and now remember why I used to take off in the middle of the night to ride this road in my car.
Road surfaces are good over-all.
There are a couple of pull-offs for views, and Turner Bend store has Pig Trail souvenirs, shirts etc, as well as cabins & camping, although we didn´t stay there.
