Great looking runner. You will really enjoy getting out on some trails this fall with it.
As for places to hit the trails in the Central AR area, I generally do day runs to the Ouachita National Forest. I'm fortunate enough to work 4 10's and have Friday off. The ONF is close enough I can make a run out there for the better part of the day and still be home in the afternoon once the family gets home. There are some really great areas to explore as you can see on my build thread.
Here is a link to a trip I took with some good friends that had never been out. We strayed from the route a little the day we were out due to wanting to explore but this will give you an idea the area I'm talking about.

If you need any suggestions let me know and I will share some more of the routes I have run.
You might also check out Central Overland. They are based out of Conway, AR and usually take a couple trips a year with several routes that all level of builds can handle.
