I'm in Alma, Arkansas, about 13 miles south of the TAT closing RT71. Have Not done the entire TAT but living so close to it every so often I hit portions of it. The stretch from Oark to the Oklahoma line is pretty nice. But the other day we did the Oklahoma to the Illinois River /Tahleqhua region and it has lots of loose gravel... it was very rough riding, however, we had pretty good precipitation/rain in the las few days and maybe got packed some. Good eating at Oark cafe, a landmark for all kinds of bikers. If I could be of any help please send me an email with your contact info and I will reply or call you. Ride safe and enjoy your ride..
