Depending how you go, Talihena OK to Mena AR is a excellent 50 + mile stretch of "mountain" ridgetop road with lots of twisties, and will deposit you at the bases of lots of good AR roads to ride including 7. The Talimena pkwy also has no truck traffic, very few cars and few bikes. Wonderful in good weather with all the vista views, a hell of a ride in a storm! Try it in good weather!
